Ion channels are proteins that are found in the cell membrane and allow the movement of ions across the membrane. They shape the physiological properties of different cell types. For example, they control the release of cytokines by immune cells, control the bioelectrical signals in neurons and cardiomyocytes which are important for cellular communication and proper functioning of the brain and the heart. All ion channels are made of multimeric subunits that assemble together to form a pore. One of the largest and most diverse family of ion channels is the voltage-gated potassium-channel. Although there are limited number of subunits (encoded by ~70 genes), each subunit can combine in different combinations, resulting in an enormous array of homomeric and heteromeric subytpes. An example of different K-channel subtypes formed by two subunits is shown in the figure below. The function of different K-channel heteromers have remained elusive due to the lack of selective pharmacology to discriminate between the heteromers. Our lab discovered and developed conotoxins as pharmacological tools to study the properties of different K-channels. Conotoxins are used by cone snails for predatory purposes- they paralyze their prey by targeting various ion channels and receptors. In our lab, we have extracted and purified conopeptides from the venom of different cone snail species. In this project, we will use conopeptides and other marine bioactive compounds to study the properties and functions of different voltage gated K-channels. We will use a technique called two-electrode voltage clamp to study the properties of K-channels. Students will gain an understanding of different concepts from molecular biology, bioelectricity and biophysics.

(collaborative project With Wayne Potts lab) The global COVID19 pandemic has uncovered the need to understand and address the roles of immune cells in combating pathogenic attacks. While initial inflammation is essential to control invading pathogens, prolonged inflammation results in “cytokine storms” with unintended consequences and pulmonary complications. Current anti-inflammatory drugs are non-selective and are often contraindicated in patients with comorbities, highlighting the need to develop drug leads that are selective and superior to current anti-inflammatory drugs. We recently developed an in vitro drug screening platform to identify marine natural products with immunomodulatory properties and identified a library of conotoxins that modulate cytokine release. In the next phase of this project, our goal is to test these drug leads in animal models of respiratory distress. Using mice infected with influenza virus (H3N2 strain) as a model system, we will test the library of conotoxins in modulating cytokine levels. Students will be exposed to animal handling techniques, dissection skills, immunostaining and ELISA assays. In addition, students will gain experience in testing drug leads using in vitro and in vivo assays that are essential for conducting pre-clinical trials.

Biological Data

December 20, 2021

Fred Adler

In an age when cross-disciplinary collaboration has become a buzzterm, especially in academia, Fred Adler puts his mathematical models where his mouth is. Multi-disciplinary work—in which academic silos are breached in the search for truth—is the hallmark of what Adler, who has a joint appointment in mathematics and biology, does.

His is the kind of work that will be supported by the new science building recently announced by the College of Science, dedicated to applied and multi-disciplinary work, and where most STEM students at the U will eventually find themselves for a time.

As Director of the Center for Quantitative Biology, Adler and his team have applied their data-driven tool kit to everything from viruses to animal behavior, and from biodiversity to infectious diseases. Who else can claim a lab’s subject models as varied as aphid-tending ants, hantavirus, and the Southern Right Whale off the coast of Argentina?

Math in Nature

The Adler group’s approach to research is driven by basic questions about how biology works. To bring together several threads of research, the lab began a study of rhinoviruses, the most common cause of the common cold, and how they routinely and rapidly change. The study uses mathematical models based on known interactions in the immune system and genetic sequences. “We hope to build detailed evolutionary models of this rapidly change set of viruses,” Adler reports.

He and his team are now looking at cancer in humans. There are, of course, hypotheses of how cancer takes over cells in the body and grows. But too many of these hypotheses are based on assumptions that cells behave as they do with complete information and clever plans for the future instead of the confusing world of a real tissue.

“However useful some of these [current] models are,” says Adler, “they are not based on a realistic assumption.” In fact, a prime contribution of the mathematical modeler is “to make sense of things from the perspective of what you’re modeling.” What access to information does the cell or organism have, is a central, guiding question.

Muskan Walia and Emerson Arehart

Part of how cancer behaviors may be better scientifically “unpacked” is through game theory but expanded over time and space and placed in a context of incomplete information between constituent parts.

Mathematical models, or more accurately, an ensemble of models later aggregated like political polls or weather models to predict the future, may be the answer. “We usually don’t get a simple smoking gun,” says Adler referring to complicated questions in biology, whether developmental, behavioral-ecological, immuno- or micro-biological. “With nine or ten big mathematical models running all the time you have a [more robust] hypothesis,” he says.

“All thinking is done using modeling,” Adler reminds us, “whether it’s through language or, in my case, mathematics.” The strength of the latter is that when mathematical modeling is added to the classical biologist’s models, it is “perfectly explicit about its assumptions. When you do the math right (and we always do), the logic leading from assumptions to conclusions is airtight ‘true.’”

This is important because a mathematical argument can’t be controverted. “If conclusions in biological research are wrong, it’s the assumptions that are wrong,” and the researcher can then pivot on those assumptions.

Modeling of this kind, of course, has proven helpful, most recently, in the study of Sars-CoV-19, the virus that has propelled the world into a pandemic. The coronavirus does not operate in isolation, but with other components through the human immune system.

This kind of work is animated not just by its predictive character using statistics—as in the case of artificial intelligence or machine learning (“We aren’t all cyborgs, yet,” Adler says)—but, it is predictive in a mechanistic sense in that it cares deeply about the more nuanced and open-ended “how,” the foundation of the scientific method.

Adler started out at Harvard as a pure mathematician, but by the time he arrived at Cornell University as a graduate student, he had discovered that he really enjoyed talking and collaborating with biologists. Stanford-based Deborah Gordon, a renowned expert on ants, which as he puts it, “achieve a lot of stuff fairly robustly through simple rules,” was one of them. He also found himself with David Winkler in upstate New York in a bird blind and observing the breeding and offspring-raising behaviors of tree swallows. The complicated models he built based on that research were never published, but Adler was hooked on life sciences.

Whether it’s modeling the lungs of cystic fibrosis patients looking for a transplant, determining that the changesnin Covid-19 are driven not just by mutations in the virus but adaptations of human immune response, or other “bench to bedside” medical science, Fred Adler has found a home in the mechanistic aspects, the “how,” of basic science.

How to synthesize his research over the past thirty years is the next big question. For now he will continue with modeling biological systems, their signaling networks based on the body’s own network of “trust” between components, and determining how those systems are corrupted… and maybe how to fix them.

Theory Meets Intuition

December 20, 2021

Will Feldman

Will Feldman, Assistant Professor of Mathematics, joined the Department of Mathematics in 2020. He studies mathematical models of physics and thinks about the things most of us take for granted, for example, fluid flow, water droplets, and flame propagation. These models are often developed by engineers or physicists using basic assumptions, but the resulting equations can be difficult or impossible to solve exactly.

“I’m interested in proving mathematically rigorous results for these models,” said Feldman. In his research, the results sometimes show the limitations of the modeling assumptions used to derive the equations. Other times, they explain the behavior of all the solutions of the equation without relying on special formulae. “And sometimes, the results are used to justify numerical computations, which are meant to approximate solutions of these equations,” he said.

One particular type of problem Feldman has studied is called “homogenization”—the study of the physical properties of complicated heterogeneous materials. The idea is to “average” or “homogenize” the complicated small-scale inhomogeneities in the material to derive simpler effective equations to describe properties at larger scales. For example, the ideas of homogenization theory can be used to study the shapes of water droplets on surfaces that have microscopic roughness, such as a plant leaf, a piece of glass, or a table top.

“I like to work out these kinds of questions because I get to use both physical intuition and theoretical mathematical tools,” he said.
Feldman wasn’t always interested in mathematics. As an undergraduate, he thought he wanted to study physics or history. He started taking math classes because math was useful in studying advanced physics. “I had a lot of amazing math professors, and I started to like math a lot,” he said. “Eventually, I realized I could maybe study math and also bring in my interest in applications (especially physics). Basically, that’s how I ended up studying partial differential equations.”

Like many undergrads who study math, Feldman was worried he would need a special talent to succeed at math, but he had supportive and encouraging mentors, so he never got too discouraged. “I hope the experience of having good mentors has taught me to be a good mentor, too, and show my students I believe in them and the many interesting possibilities available in a career in or related to mathematics,” he said.

Before joining the U, Feldman received his Ph.D. from UCLA in 2015 and was an L.E. Dickson Instructor at the University of Chicago from 2015-2019. He was also a member at the Institute for Advanced Study (IAS) from 2019-2020. The IAS is one of the world’s leading centers for curiosity-driven basic research, based in Princeton, NJ.

In 2019, Feldman was awarded the John E. and Marva M. Warnock Presidential Endowed Chair for Mathematics by the University of Utah. He will hold the chair for five years and anticipates the funding will provide new and interesting directions for his research. He hopes to have a positive impact by training, mentoring, and supporting a next generation of mathematicians. “It was a great honor to be offered the Warnock Chair,” said Feldman. “I am obviously very proud to receive the award and grateful to the Warnock family and the university.”

As he moves forward in his research, he’s been thinking about problems involving interfaces in heterogeneous media. He’s also been wondering about transport equations and models of grain boundary motion in polycrystalline materials. He’s looking forward to discussions and collaborations with his colleagues in the Math Department, especially in the applied and probability groups.
Feldman and his wife are in the midst of raising two young children. He enjoys the great hiking in Utah and is looking forward to relearning how to ski and maybe starting new outdoor activities, such as climbing and biking. He enjoys cooking and has become obsessed (during the pandemic) with making a great cup of coffee.

“A Presidential Endowed Chair at the University of Utah is one of the highest honors that we can bestow on a faculty member.” —Dean Peter Trapa

Presidential Endowed Chairs are crucial for the recruitment and retainment of the most accomplished faculty members. Through these philanthropic gifts, the faculty are able to further support their cutting-edge research and explore new areas in their field.

John E. Warnock, BS’61, MS’64, PhD’69, and Marva M. Warnock created a Presidential Endowed Chair for Faculty Development in Mathematics in 2001 through a gift of Adobe Systems stock.

Space Plants

December 20, 2021

Ming Hammond

For humanity to push the boundaries of space exploration, we’re going to need plants to come along for the ride. Not just spinach or potatoes, though—plants can do so much more than just feed us.

“There’s a lot of promise, potential and hope that we can use the tools developed in synthetic biology to solve problems.” says Chemistry Professor Ming Hammond, “not just that you would find in space, but where you have extreme limitation of resources.”

A synthetic garden.

Synthetic biology is a field that engineers biological systems. In this case, the team is looking at plants as potential bio-factories. Every organism naturally produces countless proteins as part of its biological function, so why not engineer a plant to produce, say, a needed medication or a polymer that could be useful in future long-term space exploration missions?

“The benefit is that you can take seeds with you,” Hammond said. “They’re very lightweight. They grow and gain biomass using the CO2 that we breathe out. And if those plants can produce proteins on demand—we know that plants are able to produce anti-viral and anti-cancer antibodies on a large scale.”

LED lights and USB camera.

Synthetic biology is already established on Earth. But translating that same technology to spaceflight requires different considerations. Hammond and her team encountered many of these constraints when adapting their experiment to operate within the small (10cm by 10cm) CubeSat enclosure.

For spaceflight, the team decided to engineer plants to change color as they produced the target protein, and monitor the progress with a camera. It’s an elegant and innovative solution, based on a previously published method, but adapted for the constraints of a cube in space.

Final assembly.

“We had to take something that worked beautifully in the most carefully controlled conditions,” Hammond said, “and get it to work under very harsh and challenging conditions inside the plant cube.”

The plant cube was designed with the forward vision of preparing for plant growth studies on the moon, and is a technology development step towards that goal.

The entire experiment took 10 days and appeared to show successful protein production. The results from the team, including collaborators from NASA Ames and International Space University, were published this year.

It takes a lot of time and effort to put equipment in space, and Hammond appreciates the many hours of work that the team has put in. “We are a small but dedicated group of volunteers,” she said. “People worked nonstop to fix last-minute things that came up before launch. I’m just really proud of the effort everyone’s put in.”

SpaceX Falcon 9 rocket.

Hammond and her family traveled to the NASA Kennedy Space Center to watch the Dec. 5, 2019 launch of her experiment, which was nestled within a SpaceX Falcon 9 rocket on a resupply mission to the International Space Station.

“At the launch of my experiment, we had a chance to see Bob Behnken and Doug Hurley, the two astronauts that flew the first manned SpaceX flight on May 30, 2020,” she said. “It was an amazing opportunity to share the launch with my son, (6 years old at the time), and other family members. Of all the things I’ve done in science this, for them, is the one that probably inspires the most interest and awe.”

The Frontier of Physics

December 20, 2021

The Standard Model of particle physics is the theory that explains how the most elementary particles interact with each other and combine to form composite objects, like protons and neutrons. Developed over the course of many decades, what we know as the Standard Model today was formulated nearly half a century ago and remains a focus of study for particle physicists. But by itself, the Standard Model fails to provide an explanation for many important phenomena, such as the existence of the dark matter in the universe.

The Standard Model

Today, physicists and researchers are on the frontier in the search for physics beyond the Standard Model, using connections between theoretical particle physics, cosmology, and astrophysics to help us understand the universe.

Pearl Sandick, Associate Professor of Physics and Astronomy and Associate Dean of Faculty Affairs for the College of Science, is on that frontier. As a theoretical particle physicist, she studies some of the largest and smallest things in the universe, including dark matter, which is the mysterious stuff that gravitationally binds galaxies and clusters of galaxies together.

While regular matter makes up about one-sixth of the total matter in the universe, dark matter makes up five-sixths. There are compelling arguments that dark matter might actually be a new type of elementary particle. Electrons are an example of an elementary particle—they are the most fundamental building blocks of their type and are not composed of other particles. Other examples of elementary particles include quarks, neutrinos, and photons.

In August 2019, Sandick and her colleagues hosted a workshop entitled “The Search for New Physics—Leaving No Stone Unturned,” which brought together dozens of particle physicists, astrophysicists, and cosmologists from around the world to discuss recent advances and big ideas. “It was such a vibrant environment; I think it helped us all broaden our perspectives and learn new things. Though there’s a lot going on in the meantime, we’re already excited about the prospect of hosting a second “No Stone Unturned” workshop in the new Science Building.”

Recently, Sandick has turned her attention to another cosmological phenomenon—black holes—tackling the question of how their existence affects our understanding of dark matter and other physics beyond the Standard Model.

“Some of this new research makes use of the cosmic microwave background (CMB), which is leftover radiation from the Big Bang that we can observe today,” said Sandick.

“CMB measurements can help us understand the structure and composition of the universe, including how much is made of dark matter. The CMB also can provide hints about what other particles or objects existed in the early universe.”

Before the CMB was created, the universe was very hot and very dense. In this environment, the densest places would have collapsed to become black holes. The black holes that formed in this way are called primordial black holes (PBHs), to differentiate them from black holes that form much later when stars reach the end of their lives. Heavy enough PBHs would still be around today and could make up some or all of the dark matter, providing an alternative to the idea that dark matter is a new particle. Lighter PBHs probably are not an explanation for dark matter, but they would have had an important interplay with dark matter and other new particles.

Sandick, along with a U of U postdoctoral associate, Barmak Shams Es Haghi, have been looking into the many impacts of a population of light PBHs in the early universe. Recently, they’ve completed the first precision study of some spinning PBHs in the early universe, finding that current CMB measurements from the Planck satellite (an observatory operated by the European Space Agency) and future measurements with the CMB Stage 4 experiment at the South Pole and in the Chilean desert are sensitive to many important PBH scenarios. The Planck data already point to some more and less likely possibilities, while CMB Stage 4 will be an important step forward in understanding the life and death of small black holes.

In addition to her research, Sandick is passionate about teaching, mentoring, and making science accessible and interesting. She has been recognized for her teaching and mentoring work, with a 2016 University of Utah Early Career Teaching Award and a 2020 University of Utah Distinguished Mentor Award. In 2020, she also was named a U Presidential Scholar. Women are still widely underrepresented in physics, and Sandick is actively involved in organizations that support recruitment, retention, and advancement of women physicists. She has served on the American Physical Society (APS) Committee on the Status of Women in Physics and as the Chair of the National Organizing Committee for the APS Conferences for Undergraduate Women in Physics. She is currently chair of the APS Four Corners Section, which serves approximately 1,800 members from the region. In 2011, she founded a group to support women in the Department of Physics and Astronomy and continues to serve as their faculty advisor.

She earned a Ph.D. from the University of Minnesota in 2008 and was a postdoctoral fellow at Nobel Laureate Steven Weinberg’s group (Weinberg Theory Group) at the University of Texas at Austin before moving to the University of Utah in 2011.

Arctic Adventures

December 14, 2021

Jody Reimer

Counting on Mathematicians to Help Save the Planet

On a brilliant white ice floe floating in the Arctic Ocean, a group of people in bulky coats adjust to the biting cold, having been dropped off by helicopter. “All of a sudden, I turn around and there’s a polar bear and it starts running at us,” says Jody Reimer, recounting a moment of panic. “Luckily, the helicopter swooped back in to scare the bear off, but I had the adrenaline shakes for the rest of the day,” she adds, laughing.

You might expect such a nail-biting anecdote to come from an explorer, but Dr Reimer is a mathematician and lecturer at the University of Utah, as well as being part of a community that has swapped cosy classrooms for some of the Earth’s most inhospitable wildernesses, in a bid to use numbers to understand global warming.

Their adventures enable them to observe first-hand the processes driving change in the polar regions and validate their mathematical theories of sea ice and its role as a critical component in the Earth’s climate system.

A complex problem
The thickness and extent of sea ice in the Arctic has declined quickly since satellite measurements were first taken in 1979.

Sea ice is the Earth’s refrigerator, reflecting sunlight back into space. Its enduring presence is important to our planet’s future because, as more ice melts, more dark water is exposed which absorbs more sunlight. This sun-warmed water melts more ice in a self-reinforcing cycle called ice albedo feedback.

While sea ice decline is perhaps one of the most visible large-scale changes connected to planetary warming on the Earth’s surface, analysing, modelling and predicting its behaviour and the response of the polar system it supports is incredibly difficult, but mathematicians can help.

Kenneth Golden, a distinguished professor of mathematics and adjunct professor of biomedical engineering at the University of Utah, has built a unique sea ice programme over 30 years. Its combination of mathematics research, climate modelling and exciting field expeditions, has attracted students and postdoctoral researchers, including Dr Reimer, who are focused on using this type of science to help tackle the pressing challenges of a rapidly changing climate.

Factoring in animals
Dr Reimer has studied how polar bears and seals respond to changes in their frozen environment. While she used mathematical models to understand the interactions between these creatures and their habitat, she also took measurements and samples from bears in the Arctic, which was something she never expected to do as a mathematician. “They’re not totally sleeping when they are tranquilised; they’re groggy,” she explains. “One of them freaked me out because it seemed like it could wake up at some point.”

Their shrinking habitat means polar bears are walking on thin ice, but it’s hoped that studies like Dr Reimer’s will help experts understand how to protect the majestic predators.

However, it is the “mind-blowing” microscopic world of bacteria and algae that live in salty water pockets inside the sea ice that now excites her. This biological community and its habitat are influenced by changes in temperature, salinity and light, making it difficult to model accurately. In her current work, Dr Reimer constructs models to understand how these factors interact to determine biological activity within the ice. “Understanding how processes on these small scales contribute to macro-level patterns is critical to modelling the impact of a warming climate on polar marine ecology,” she explains.

Crunching the numbers on salty ice
It is the challenge of understanding how the microscopic structure of sea ice affects the behaviour of massive expanses of ice that interests Prof Golden. He has visited the Earth’s polar regions 18 times, braving the westerly winds known as the “Roaring Forties” to reach Antarctica by ship and narrowly avoiding plunging into icy waters while measuring sea ice. “One time I was visited by a massive whale about eight feet away, who could easily have broken the thin floe I was on with a casual flick of its tail,” he says.

Ken Golden

Prof Golden studies the microstructure of sea ice to calculate how easily fluid can flow through it. “Sea ice is salty. It has a porous microstructure of brine inclusions which is very different from freshwater ice,” he says.

Prof Golden has led interdisciplinary teams to predict the critical temperature at which the brine inclusions connect up so that fluid can flow through sea ice, and to develop the first X-ray tomography technique to analyse how the geometry of the inclusions evolves with temperature. “Understanding how seawater percolates through sea ice is one of the keys to interpreting how climate change will play out in the polar marine environment,” he explains.

Discovering this “on-off switch” has helped scientists better understand processes such as how nutrients that feed algal communities living in the brine inclusions are replenished.

The brine in sea ice also affects its radar signature, which affects satellite measurements of parameters like ice thickness used to validate climate models. These models are important because they predict future changes to our climate and are used by world leaders and scientists to come up with mitigation strategies.

Coming in from the cold
The variety of ice presents a challenge, but diversity among researchers, teachers and students creates the perfect environment for fresh ideas. In the US, just one quarter of doctoral degrees in mathematics and computer sciences were awarded to women in 2015, but schemes such as the University of Utah’s ACCESS programme are nurturing talented female mathematicians by helping them unlock opportunities such as mentoring and hands-on research. Expeditions to the Arctic not only give students an elevated experience, but ensure mathematicians are involved in cutting-edge research and solutions, alongside climate scientists and engineers.

When they are not battling blizzards, Dr Reimer and Prof Golden work on collaborative, interdisciplinary projects and co-mentor female undergraduate students as part of the ACCESS programme. After refreshing the mathematics component in 2018 to include climate change, Prof Golden has seen roughly triple the number of ACCESS students interested in taking a maths major or research placement than before.

Rebecca Hardenbrook, who is one of Professor Golden’s PhD students, says: "focusing on pressing issues like climate change attracts more of the people we want into mathematics, which is everyone, but in particular, women, people of colour, queer people; anyone from an underrepresented background.”

Rebecca Hardenbrook

Pooling resources
Hardenbrook joined the ACCESS program ahead of her first year as an undergraduate, spending the summer in an astrophysics lab, which opened her eyes to the possibility of doing research. "It was really life changing," she says, not least because she further decided to pursue a PhD in mathematics with Prof Golden after studying thermal transport through sea ice as an undergraduate.

She now inspires younger students on the ACCESS scheme as a teaching assistant, as well as modelling melt ponds, which are pools of water on the Arctic sea ice. These ponds play a decisive role in determining the long-term melting rates of the Arctic sea ice cover by absorbing solar radiation instead of reflecting it. As they grow and join together, they undergo a transition in fractal geometry, effectively creating a never-ending pattern that can be modelled by mathematicians.

Hardenbrook is building upon a decade of work on melt ponds by Prof Golden and previous students and researchers at the university by adapting the classical Ising model, which was developed more than a century ago and explains how materials can gain or lose magnetism, to model melt pond geometry. “I hope to make the model for sea ice more physically precise so that it can be put into global climate models to create a more accurate approach of addressing melt ponds, which have a surprising effect on the albedo of the Arctic,” she explains.

Adding to the big picture
Mathematicians have already solved the conundrum of how to define the width of the undulating marginal sea ice zone, which extends from the dense inner core of pack ice to the outer fringes , where waves can break the floating ice.

Court Strong, who is an atmospheric scientist and one of Prof Golden’s colleagues at the University of Utah, drew inspiration from an unusual source: the cerebral cortex of a rat’s brain. He realised they could use the same mathematical method to measure the width of the marginal ice zone as they do for measuring the thickness of the rodent’s bumpy brain, which also has a lot of variation. With the aid of this simplified model, the team was able to demonstrate that the marginal ice zone has widened by around 40% as our climate has warmed.

The university of Utah’s ACCESS scheme, including its hands-on research, immerses students in an interdisciplinary environment where maths is part of a bigger picture. It encourages cross pollination, where methods and ideas from seemingly unrelated areas of science can be used to solve problems when the underlying mathematics is essentially the same.

“When you’re presented with an unusual situation, you need different kinds of minds to look at a problem clearly and come up with solutions,” says Prof Golden.

The loss of sea ice seen in the Arctic has happened over just a few decades and continues at an alarming pace.

“We need all the good brains and different ways of thinking that we can get, and we need them fast,” he says.

ACCESS Testimonials

December 8, 2021

ACCESS Class of 2018

The ACCESS program opened my eyes to the interconnected nature of all aspects of STEM and some humanities. This encouraged me to broaden my understanding of STEM concepts by taking a multidisciplinary view and by examining the same topic from many different perspectives. Aside from opening my eyes in an academic setting, ACCESS also connected me with a network of intelligent women in STEM who I am fortunate to have met.

The opportunity to meet strong-minded and dedicated women in STEM disciplines was so empowering. Amazing friendships were gained, class was intriguing every day, and the opportunity to explore various STEM majors was invaluable.

One of the most rewarding [elements of ACCESS] was engaging with a community of other young women, both inside and out of the classroom. I found that I could engage in enthusiastic discussions about classroom projects with my peers. I think that our mutual excitement, when it comes to science-related topics, really brought us together as a community and created a supporting group of friends who also understand some of the unforeseen challenges that come with studying science as a woman. I really enjoyed having the opportunity to talk to women who are members of the science or engineering faculty… hearing from them in class on the diversity of topics they study and getting advice from them one on one really strengthened my interest in many STEM disciplines. Ultimately, this exposure led me to realize I wanted to change my major to one I hadn't even considered going into ACCESS.

I really enjoyed getting a head start on my education at the U. It gave me time to adjust to becoming a college student and understand what it means to be totally in charge of my own education. It really helped me look at what I would like to do in the future and I made so many new life-long friends.

ACCESS Class of 2017

As a first-generation student, the [ACCESS] summer program helped me integrate more easily into college life and provided me with an incredible support system.

My research experience helped me to appreciate how science is used in the real-world, and helped me to step out of my comfort zone and explore areas I never would have thought of.

ACCESS Class of 2011

For my ACCESS research experience, I worked in an astronomy lab which mostly meant teaching myself how to program. After spending the better part of a month fixing a bug in my code, I thought there must be a better way! I started taking computer science classes, and I've been looking for better ways to write code ever since. I'm now pursuing a PhD in computer science and love it. I'm not sure I would have found my way here if I hadn't started working in that astronomy lab as a freshman, so thank you ACCESS!

ACCESS Class of 2010

Without ACCESS I probably would never have entered and remained in the field of engineering! At times it was difficult to attend classes with so few women or work in a male dominated field. ACCESS showed me that there were many other like-minded, strong, and intelligent women who were also passionate about science and engineering, and that I was not alone in my pursuits!

There are many opportunities that have had tremendous impact on my life… but the ACCESS Program was and is one of the most influential. The program, which introduced different perspectives and sides of the sciences in a very hands-on way, has helped inquisitive minds develop skills essential for success in STEM. I gained lifelong friendships with my fellow classmates and an even greater support network. I've never felt isolated being a woman in STEM. I've learned to find value in myself as a scientist and in others.

ACCESS Class of 2008

My research focuses on developing and utilizing biophysical analyses to establish the complex molecular pathways in immune and epithelial cell biology (PhD candidate, Rice University). ACCESS was the perfect foundation I needed to succeed as a woman in STEM.

ACCESS Class of 2006

I'm so grateful to ACCESS for the start it gave me. I never thought I would become a geologist. I started out as a physics major and quickly realized it wasn't for me. My academic success all started with ACCESS and especially with exposure to research during my first-year of college, without which I would not have gotten a position in an environmental engineering lab. This introduction changed my academic goals and set me on path for my future career. I graduated from the University of Utah with degrees in Geology and Geological Engineering and went on to become an NSF Fellow at the Ohio State University, where I graduated with a Master's degree in Geochemistry.

I graduated with Mathematics and Biology degrees from the U, earned a PhD in biology at the University of Washington, and started working in science policy. I have worked as an Associate Program Officer at the National Academies of Sciences, and currently am a AAAS Fellow, in a congressional office. It all started in ACCESS, a program that changed the course of my education and life.

ACCESS Class of 2002

I'm very grateful to the ACCESS program. I think the biggest thing I learned is that women are often doing much better than they think. During the ACCESS physics module, the instructor told us how females will get Bs, and think they are failing and drop out of the sciences. While males, in the same courses, will get Cs and think they are doing awesome!

ACCESS Class of 1997

I want to applaud the existence of programs like ACCESS and the strong individuals who put tremendous effort and patience into their coordination. If equal representation and continued innovation are of true concerns, these programs and their coordinators demand the utmost respect and investment.

SRI Update

December 2, 2021

Many undergraduates major in science in the hope of doing research someday. The College of Science’s Science Research Initiative (SRI) is an innovative new program that puts students in a lab as soon as they arrive.

“The most consequential learning happens by doing, and that is especially true in the College of Science. Experiences in a laboratory-centered, team-based, interdisciplinary environment give students the skills to succeed and access opportunities in high-paying industries,” said Peter Trapa, Dean of the college. “The SRI offers incoming students, with no prior exposure to research, the opportunity to learn alongside their peers to gain hands-on, technical expertise, and learn directly from researchers as early as their first year at the U. The college’s exceptional faculty, world-class research facilities, and commitment to in-person experiential learning makes this unique program possible.”

Learning by doing.

Any student admitted to the College of Science can apply. During the first semester, the cohort of SRI undergraduates take a course that prepares them to work in a research lab. The course teaches principles of scientific inquiry, introduces students to the breadth of research in the College of Science, and breaks down the structure of a lab, such as the roles of graduate students, postdoctoral researchers, and the principal investigator. After learning about the research projects, known as research streams, the students rank the labs they’d most like to experience. The program matches them to a SRI faculty scientist leading the project where they will work during the second semester. Then, SRI mentors help each student figure out a path forward, whether it be continuing with the research stream, switching projects, or even finding alternatives to lab-based research.

The SRI is led by three scientists and educators who specialize in diverse disciplines. Dr. Joshua Steffen, Assistant Professor Lecturer of Biology, leads a research stream that uses metagenomic approaches to understand generalist foraging behaviors. Dr. Ryan Stolley, Associate Instructor of Chemistry, leads a research stream building an underexplored class of molecules. Dr. Heather Briggs, Associate Instructor for the College of Science, leads a research stream focused on understanding how microbial communities in flower nectar impact the way pollinators interact with plants.

Joshua Steffen

“We want to give as many students as possible in the College of Science a research experience as soon as they get here, totally independent of grades or previous experience. We’re different than other research programs because we remove a lot of the barriers that typically exist to getting into a lab. It can be intimidating to talk with faculty. We have a structured program that navigates that for the student. It’s also about building community. Research opportunities are one reason why you come to a big university like the U, but it’s easy to get lost and it can be hard to develop a community. We’re also hoping that this can help students connect with peers and mentors that they can rely on.”

Heather M. Briggs

“There is often a disconnect between how we do science and how we teach science. At the SRI we empower students to work through hypothesis generation, experimentation, and interpretation. This holistic process encourages a deeper understanding of concepts in practice and allows our students to take responsibility for their own learning. The SRI experience provides a supportive learning environment that fosters self-generation of ideas and ultimately a continued interest in research science.”

Ryan Stolley

“SRI benefits students, but it’s also a great opportunity for faculty. We work with faculty to write SRI into the broader impacts section on grants. But also, most researchers will have an undergraduate researcher at some point—it’s sometimes a roll of the dice on how they perform. Now, we can have a structured program that has specific goals, outcomes, and it can train these students. And the faculty has the freedom to manage them as they want. We’d love to get excited researchers into the fold and pair them with students who are excited by the work they’re doing.”

Benning Lozada

A student majoring in biology who had previously worked in research labs. He applied to the SRI to get experience in a field he was passionate about.

“I wanted to get involved in research because it’s really important for graduate school. But it’s really difficult to do. You have to cold call or email professors and, often times, they don’t have a place for you. I think this program is really useful because the environment is more teaching focused. So, you’ll be able to learn the skills that you need to, if you want to eventually go out and do research in other areas. It gives you a good basis as to what research looks like, so that you’re prepared for that in the future. You don’t always get that training when working in labs.”

Nayma Hernandez

A third-year biology major who transferred to the U. “It was really hard to get into research where I transferred from because not every professor wants an undergraduate, and you’re not the only one trying. And here, well, as long as you’re in the program, you’ll be able to participate in research.

I think it’s always good to do some research, even if you don’t think you want to go to grad school. It’s always good to try something because you might end up liking it. I’ve had some students tell me that they changed careers because they ended up doing research and they’d rather do that. The SRI program gives you that initiative to actually start doing research.”

Give to the SRI

Demand for the Science Research Initiative is skyrocketing. More than 150 students have enrolled this year, and we are planning for 300 by fall of 2022.

Experiences in a laboratory-centered, team-based, interdisciplinary environment give students the skills to succeed and access opportunities in high-paying industries.
We know the majority of our students work at least part-time to make ends meet, and it is hard for many of these students to work in the lab instead of picking up hours at their jobs. Our goal is to remove this financial barrier by providing ongoing support for every science student who needs a scholarship.

If you would like to donate to the Science Research Initiative, the College of Science will match your donation dollar-for-dollar up to $50,000. Your donation can go further and help us provide this unique experience to more students. For more information please call 801-581-6958, or visit science.utah.edu/giving.
