Sky Survey Data Releases 2 Million Stellar Objects

The universe is big, and it’s getting bigger.

To study dark energy, the mysterious force behind the accelerating expansion of our universe, scientists are using the Dark Energy Spectroscopic Instrument (DESI) to map nearly 40 million galaxies, quasars and stars. Today, the collaboration publicly released its first batch of data, with nearly 2 million objects for researchers to explore.

The 80-terabyte data set comes from 2,480 exposures taken over six months during the experiment’s “survey validation” phase in 2020 and 2021. Between turning the instrument on and beginning the official science run, researchers made sure their plan for using the telescope would meet their science goals—for example, by checking how long it took to observe galaxies of different brightness, and by validating the selection of stars and galaxies to observe.

“The fact that DESI works so well, and that the amount of science-grade data it took during survey validation is comparable to previous completed sky surveys, is a monumental achievement,” said Nathalie Palanque-Delabrouille, co-spokesperson for DESI and a scientist at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), which manages the experiment. “This milestone shows that DESI is a unique spectroscopic factory whose data will not only allow the study of dark energy but will also be coveted by the whole scientific community to address other topics, such as dark matter, gravitational lensing and galactic morphology.”

Kyle Dawson

DESI uses 5,000 robotic positioners to move optical fibers that capture light from objects millions or billions of light-years away. It is the most powerful multi-object survey spectrograph in the world, able to measure light from more than 100,000 galaxies in one night. That light tells researchers how far away an object is, building a 3-D cosmic map.

“This new sample represents the first science-quality data taken with this powerful new instrument. These survey-validation data are better quality and provide spectra and classification of a wider range of stars, galaxies and quasars than the data we expect in the main five-year program,” said Professor Kyle Dawson. Dawson of the University of Utah was one of the two primary leads of the survey validation effort and is also DESI co-spokesperson.  “We have learned from these data how to build the most effective cosmology program.”

Tommaso de Fernex, Math’s new department chair

Tommaso de Fernex is stepping into the role of Chair of the Department of Mathematics following Professor Davar Khoshnevisan’s notable six-year term.

“It is with great anticipation that I step into the seat of Chairman of the Department of Mathematics,” says de Fernex, who begins the role on July 1. “I am honored for this appointment and humbled by the faith the College of Science has in me. Under the strong leadership of Davar Khoshnevisan, the Department has been on a great upward trajectory, reaching new heights with exemplary faculty recruitment and record recognition, grants, and scholarships for undergraduate and graduate students. Davar and I have collaborated for some time about the outlook of the department and I see a bright future. I am fortunate to belong to such a community, with a first-class faculty, fantastic staff, impressive students, and postdoctoral fellows. I am looking forward to serving the Department in the coming years.”

“Tommaso is the perfect person to lead the Department of Mathematics,” said Peter Trapa, dean of the College of Science. “His towering international reputation and previous leadership experience will serve him well as he takes the department to new heights.” Trapa also took a moment to thank outgoing chair Davar Khoshnevisan. “I am grateful for the six years that Davar served in this role. He skillfully navigated the upheaval of the pandemic, hired an exceptional cohort of new junior faculty,  and significantly advanced the research and educational missions of the department.”

De Fernex is a recipient of the National Science Foundation Grant from 2020 through 2023 and has contributed to nearly 50 publications, with more than 50 invitations to conference talks.

Former Associate Department Chair from 2017 to 2019, De Fernex works in algebraic geometry. The main focus of his research has been on the study of singularities and birational geometry of algebraic varieties and the structure of arc spaces and other valuation spaces. He started his studies in Italy, obtaining his Laurea in Mathematics (summa cum laude) at the University of Milano in 1996 (roughly the equivalent of a B.S.) and completing a Dottorato di Ricerca in Mathematics (the equivalent of a Ph.D.) at the University of Genova in 2001. During these studies, de Fernex spent one semester visiting the University of Hong Kong in 1999 and then moved to the U.S. where he obtained a Ph.D. in Mathematics at the University of Illinois at Chicago in 2002.

From 2002 to 2005, de Fernex was a Hildebrandt Research Assistant Professor at the University of Michigan and spent the academic year of 2005-2006 as a member of the Institute for Advanced Studies before joining the faculty at the University of Utah.

As incoming chair, de Fernex will continue his passion for algebraic geometry with focus on the study of singularities and birational geometry of algebraic varieties such as log canonical thresholds, multiplier ideals, questions of rationality and the structure of arc spaces and other valuation spaces. In fact, he’s scheduled to speak in December of this year in Pipa, Brazil at a conference on “Algebraic Geometry and Related Topics.”

Dirtiest snow-year in the Wasatch accelerated snowmelt by 17 days

As the shrinking Great Salt Lake exposes an ever-growing area of its lakebed, wind-blown dust becomes more dangerous for those living in Utah’s most populous region. It also makes the snowpack dirty, which threatens the state’s most precious resource—water.

“You might see 17 days and think it’s no big deal, but our current snowmelt models don’t account for dust,” said McKenzie Skiles, assistant professor of geography at the U and senior author of a new study in which researchers analyzed the impact of dust on Utah snow during the 2022 season. They found that 2022 had the most dust deposition events and the highest snowpack dust concentrations of any year since observations began in 2009on the paper. “So, the snow is melting, water is coming out earlier and faster than we expect it to, and we’re not prepared to use it in the most efficient way. The landscape is also not expecting the water earlier, so it impacts watershed functionality as well as water availability downstream.”

The study published on June 15, 2023, in the journal Environmental Research Letters.

In 2018 Skiles authored a study that found that a single dust event accelerated snowmelt in the Wasatch by one week. That paper identified the Great Salt Lake as a relatively new dust source due to historically low water levels. Subsequent years of prolonged drought, increased evaporation and sustained agriculture and domestic water consumption drove the Great Salt Lake to record lows in 2021 and 2022 and exposed even more dry lakebed.

“Anecdotally, we kept saying, ‘This is crazy—this is the dirtiest snow in the Wasatch I’ve seen since I started making observations,’” said Skiles. “Ultimately, after we analyzed everything, it was the dirtiest year.”

You don’t need a weatherman to know which way the dust blows …

Derek Mallia

… you need co-author of the study Derek Mallia, a research assistant professor in the Department of Atmospheric Sciences at the U. Strong winds can loft dust into the atmosphere and degrade air quality, which can trigger yellow or red air pollution warnings. Dust-on-snow deposition requires a specific set of factors; nearby dust sources, relatively dry conditions and winds that are strong enough to loft dust into the atmosphere. Mallia developed a dust transport model that can pinpoint where the dust on snow originated by synthesizing meteorological and soil data. For every dust event, Mallia ran his model to identify dust sources that were responsible for accelerating snow melt in the Wasatch Mountains.

“We were expecting large areas like the Great Salt Lake Desert to be a major source of dust, but we were somewhat surprised that we observed such large contributions of dust coming from the Great Salt Lake, and especially Farmington Bay. While the lake’s dust sources are much smaller than the West Desert in terms of area, the exposed dry lakebeds are much closer to the Wasatch Mountains,” said Mallia. “These results suggest that the Great Salt Lake is an important factor when it comes to accelerating snow melt across the Wasatch Front and will become a bigger player if it continues to shrink.”

Ramón Barthelemy wins 2023 LGBTQ+ Educator of the Year

The U physicist was one of three winners of the 2023 Out to Innovate Awards that recognizes outstanding achievement by LGBTQ+ people in STEM.

When asked how his life experiences have shaped his perspective as an educator, Dr. Barthelemy said, “…being queer has impacted how I think about binaries. I do not see the world as a place where there is one incorrect and one correct answer. Rather I see a very complex world in which multiple kinds of explanations and models can be used to understand our lives and the world around us. As a scientist, this dips into ideas of philosophy of science and how we are not necessarily claiming to have a T truth, but instead are working to develop and refine models that help us explain and predict the natural world.”

His nominators noted, “…he combines stellar graduate work in physics education research with some of the deepest and most significant work on gender and LGBTQ+ issues in physics that has so far been written.” When asked what advice he would give his younger self and scientists just beginning their adventures in physics, Barthelemy “…would tell a younger version of me to trust myself and to build a community of people who support one another and want to see each other succeed.”

The announcement of the award comes during National Pride Month.

Atomic-Scale Geometry

How Atomic-Scale Geometry Might Shape the Future of Electronics

Twistronics could illuminate a path to superconductivity, revolutionize electronic devices, or perhaps hasten the arrival of quantum computing

 

Mathematicians at the University of Utah have discovered that, by twisting one square lattice over another, composite materials based on the resulting bilayer moiré pattern display electrical and physical properties that can change quite abruptly. Their findings echo twistronics, the science of twisting atomic lattices, and on some rather complex geometric principles. The discovery could have implications for a wide variety of industries, as engineers might be able to precisely calibrate the electrical, optical, thermal, or even acoustic properties of these materials. Specifically, twistronics and aperiodic geometry might soon illuminate a path to higher-temperature superconductivity, revolutionize electronic devices, or perhaps even hasten the arrival of quantum computers.

“We rotated and dilated two regular lattices relative to one another, creating a veritable zoo of microgeometries—and some incredible patterns emerged,” says Ken Golden, distinguished professor of Mathematics at the University of Utah and senior author of the study.

“The resulting moiré provides a template for the geometrical arrangement of two component materials, that, together make up a new twisted bilayer composite,” he tells Popular Mechanics. Imagine chicken wire lattices layered on top of each other; these can be twisted one relative to another and form entirely new moiré scales of periodicity or non-periodicity.

The ‘Rite Stuff

THE ‘Rite Stuff

A U planetary scientist helped analyze and name the heavenly culprit behind a raucous boom heard by thousands

Jim Karner has trekked almost annually to Antartica on expeditions looking for meteorites. The research associate professor in the Department of Geology and Geophysics has probably seen and handled more cosmic debris than most will see in a lifetime. But on the morning of August 13, 2022, he—along with the rest of the northern Wasatch Front—heard one explode, for the first time.“That was really loud,” he remembers thinking as he stood in his driveway. “My immediate thought was, ‘Wow, that sounds like what people have described as meteorites exploding and breaking the sound barrier.’ ”

Within days, a piece of what would eventually be named the Great Salt Lake meteorite made its way into Karner’s hands, giving him and the U an opportunity to learn what secrets of space this chunk of rock brought with it to the Salt Lake Valley.

SRI Stories

Information Engines Pay the Piper

 

Physicists sometimes get a bad rap. Theoretical physicists even more so. Consider Sheldon Cooper in the TV sit-com The Big Bang Theory:


Sheldon
: I’m a physicist. I have a working knowledge of the entire universe and everything it contains.
Penny: Who’s Radiohead?
Sheldon: (after several seconds of twitching) I have a working knowledge of the important things in the universe.

Mikhael Semaan

But a working knowledge of anything is always informed and arguably improved — even transformed — by robust and analytical “thought experiments.” In fact, theoretical physics is key to advancing our understanding of the universe, from the cosmological to the particle scale, through mathematical models.

That is why Mikhael Semaan, Ph.D. and others like him spend their time in the abstract, standing on the figurative shoulders of past giants and figuring out what could happen . . . theoretically. That Semaan is also one of the celebrated postdoctoral researchers/mentors in the Science Research Initiative (SRI), is a coup for undergraduates at the University of Utah who “learn by doing” in a variety of labs and field sites.

“The SRI is awesome,” Semaan says. It’s “a dream job where I can continue advancing my own research while ‘bridging the gap’ in early undergraduate research experiences, giving them access to participation in the cutting edge alongside personalized mentoring.”

Want to learn how to bake something? Hire a baker. Better still, watch the baker bake (and maybe even lick the bowl when allowed). And now that Semaan’s second first-author paper — done with senior investigator Jim Crutchfield of UC Davis, his former PhD advisor — has just “dropped,” students get to witness in real time how things get done, incrementally adding to the trove of scientific knowledge that from past experience, we know, can change the world.

Theory’s abstraction lets us examine certain essential features of the subjects and models we study, which in Semaan and Crutchfield’s case concern the first and second laws of thermodynamics. Is it possible to run a car from the hard drive of a computer? In the parlance of this brand of physics, the short answer is, “Yes, theoretically.”

Thermodynamics of Information Processing

From that question as a jumping off point, Semaan explains further. “The primary impact of our contribution is, for now, mostly to other theorists working out the thermodynamics of information processing. … [W]e suggest a change in viewpoint that simplifies and unifies various preceding lines of inquiry, by combining familiar tools to uncover new results.”

The physicist and writer C.P. Snow said that the first three laws of thermodynamics can be pithily summarized with, “You can’t win. You can’t even break even. You can’t stay out of the game.” Semaan elaborates on the second law, “the universe must increase its entropy — its degree of ‘disorder’ — on average…[b]esides offering an excuse for a messy room, this statement has far-reaching implications and places strict limits on the efficiency of converting one form of energy to another … .”

These limits are obeyed by everything from the molecular motors in our bodies to the increasingly sophisticated computers in our pockets to the impacts of global industry on the Earth’s climate and beyond. Yet in the second law’s case, there’s a catch: it turns out that information in the abstract is itself a form of entropy. This insight is key to the much-celebrated “Landauer bound:” stated simply, learning about a system — going from uncertainty to certainty — fundamentally costs energy.

But what about the converse situation? If it costs energy to “reduce” uncertainty, can we extract energy by “gaining” it — for example, by scrambling a hard drive? If so, how much?

Ratchet Information

To answer this question, previous researchers, including Crutchfield, imagine a “ratchet” which moves in one direction along an “information tape,” interacting with one “bit” at a time. As it does so, the ratchet modifies the tape’s statistical properties. That “tape” could be the hard drive in your computer or could be a sequence of base pairs in a strand of DNA.

“In this situation, by scrambling an initially ordered tape, yes: we can actually extract heat from the environment, but only by increasing randomness on the tape.” While the second law still holds, it is modified. “The randomness of the information in the tape is itself a form of entropy,” explains Semaan further, “and we can reduce the entropy in our thermal environment as long as we sufficiently increase it in the tape.”

In the literature, the laws bounding this behavior are termed “information processing second laws,” in reference to their explicit accounting for information processing (via modifying the tape) in the second law of thermodynamics. In this new paper, Semaan and Crutchfield uncover an “information processing first law,” a similar modification to the first law of thermodynamics, which unifies and strengthens various second laws in the literature. It appears to do more, too: it also offers a way to tighten those second laws — to place stricter limits on the allowed behavior — for systems which have “nonequilibrium steady states.”

Non-equilibrium steady state systems — our bodies, the global climate, and our computers are all examples — need to constantly absorb and dissipate energy, and so stay out of equilibrium, even in “steady” conditions (contrast a cup of coffee left out: its “steady” state is complete equilibrium with the room).

“It turns out,” says Semaan, “that in this case we must ‘pay the piper’:  we can still scramble the tape to extract heat, but only if we do so fast enough to keep up with the non-equilibrium steady states.” To demonstrate their new bound, the authors cooked up a simple, tunable model to visualize how much tighter the new results are with concrete, if idealized, examples. “This sort of idealization is a powerful tool,” says Semaan, “because with it we can ‘zoom in’ on only those features we want to highlight and understand, in this case what having nonequilibrium steady states changes about previous results.”

This uni-directional “ratcheting” mechanism may, in fact, someday lead to engineering a device that harnesses energy from scrambling a hard drive. But first, beyond engineering difficulties, there is much left to understand about the mathematical, idealized limits of this behavior. In other words, we still have a ways to go, even “in theory.” There are plenty of remaining questions to address, the fodder for any theoretical physicist worth their salt.

Complex Systems

However, far from being “only” a theoretical exercise, says Semaan, “these continued extensions, reformulations, and corrections are necessary for us to be able to understand how real-world, highly interconnected, complex systems,” like the human body, forest ecosystems, the planetary climate, etc., “exploit (or don’t) the dynamical interplay between energy and information to function. Since so many of the intricate systems we see in nature (including ourselves) exhibit non-equilibrium steady states,” he continues, “this is a [required] step to understanding how they [do this].”

Information ratchet system: At each time step, the ratchet moves one step to the right along the tape, and interacts with one symbol at a time. As it does so, it exchanges energy in various forms with its environment — signified by the T, aux, and λ bubbles in the picture. After running for a long time, the “output tape” generated by the interactions with the ratchet has different statistical properties compared to the “input tape” it receives. The information processing first and second laws are statements about the fundamental relationship between the energy exchanged with the environment and the information processing in the tape. Credit: Semaan and Crutchfield.

This is heady stuff, and the Southern California native is positively thrilled to be sharing it with young, eager undergraduates at the U through the SRI. Semaan is keenly aware of how critical the undergraduate experience in research needs to be to turn out future physicists. A son of Lebanese immigrants who both attended college in the U.S., neither were research scientists and no one he knew had studied physics. At California State University, Long Beach, where Semaan first declared electrical engineering as his major, he was “seduced into physics” through a series of exceptional and inspirational mentors. In the SRI, he hopes to carry this experience forward, and open new doors for undergraduate students.

It was the Complexity Sciences Center at UC Davis, when he applied to graduate school, that caught his attention because of its interdisciplinary nature and concern with systems in which “the whole appears to be greater than the sum of its parts.” The study of emerging systemic behaviors, helmed by Crutchfield, the Center’s Director, ultimately inspired both his PhD and his decision to join the SRI, working with students across the entire College of Science.

Following the third law of thermodynamics, Mikhael Semaan clearly “can’t stay out of the game” (nor would he want to), but one could argue he’s more than breaking even at it.

The release of this paper, titled “First and second laws of information processing by nonequilibrium dynamical states” in the journal Physical Review E is proof of that.

Bones of the Earth

“There’s always been this idea that my family has a relationship with the bones of the Earth,” says Kevin Mendoza.

The graduate student in the Department of Geology & Geophysics descended from the developers of the Nacia mine in Chihuahua Province. He recalls as a child his grandmother showing him jars of rocks from the mine given to her by her father, one of the only possessions she took with her when she immigrated to the states. A Ph.D. candidate in geophysics, Mendoza is the recipient of the 2023 University of Utah Teaching Assistantship Award: Pythonizing Geoscience Instruction. Mendoza received the award for his contributions to geoscience undergraduates. He used the assistantship to develop python programming-based core curriculum.

Mendoza joined the U after attending the University of California, Merced for his undergraduate degree where he double-majored in physics and Earth systems science. His passion for studying the deep Earth came both from his early geology lessons with his grandmother, as well as the active outdoor lifestyle his dad cultivated in him from an early age. “It was rare for any of my classmates to like even the more accessible activities like hiking, and for the Latinx students such as myself, [it was] completely unheard of at that time. I’m grateful both my parents encouraged exploration of what was then an unconventional hobby.” In high school, Mendoza was particularly passionate about gold prospecting, which he did almost every weekend in the nearby San Gabriel Mountains. He continued his wilderness ramblings in the Sierra as a park ranger in Yosemite National Park during college.

Magnetotellurics

Although his ancestors have been students of the Earth for generations, Mendoza is the first in his family to study it academically. His background prepared him to do a different type of prospecting: for electrical fields within the Earth. His research under the late Philip Wanamaker operates in the niche field of magnetotellurics (MT), which uses natural underground electrical currents to study the structure of the Earth. MT is such a specific subfield of geophysics that there are only a handful of programs across the country, including at the U. “What I do is use solar wind and lightning to basically CT scan the deep Earth,” summarizes Mendoza. From the results of this “CT scan” he can measure the water contained in the geologic water cycle, which has important consequences for plate tectonics. One of the advantages of MT is that it is more sensitive than other techniques such as seismology. “In some situations, like looking for critical battery metals and hidden geothermal resources, MT is one of the best methods for exploring mineral structures.”

Mendoza’s data comes from monitoring the voltage and magnetic field in the deep Earth with sensors deployed on the surface. In the field, these sensors are set up by placing magnetic coils and wires stretching along cardinal directions, and occasionally a coil pointing upwards. These sites are left to collect data for a few months at a time before they are relocated. Since the equipment is portable and non-invasive, MT sites are placed virtually anywhere that’s interesting geologically.

One of the main challenges with MT is visualizing the high dimensionality of the data. While common to other fields, like data science and machine learning, it takes on a unique flavor within MT. Each MT station produces nearly four times more data dimensions than seismic stations do. Complex mathematics are needed to transform this data to usable geologic models. One of the models that Mendoza works with uses over 2.5 million parameters. Analyzing the data and models is only possible using cutting-edge supercomputing tools. As part of his dissertation, Mendoza plans to provide a massive Python codebase that will help other researchers explore similar datasets.

Putting carbon back underground

While his dissertation is focused on more fundamental aspects of plate tectonics across the western U.S., Mendoza believes these findings can have application elsewhere. “Two of the biggest challenges we face with climate change are how to transition to a carbon-free economy and how to put carbon back underground. The tools I’ve developed and am developing can directly help these efforts by monitoring how stable our sequestered carbon is, or assessing the likelihood that critical metals like copper, cobalt, and lithium are in rocks hidden by deep sediment cover. These efforts require the same 2D, 3D, and 4D geophysical modeling, visualization, and evaluation techniques I’m currently using in my own research.”

That codebase will also be helpful for industry, which is possibly the endgame for Mendoza.  Having briefly worked as a geotechnician after graduating with his bachelor’s, he understands that a career in academia is not a realistic or desirable path for every student. “My personal philosophy is that universities are hybrids between a job training program and a liberal education. So, we can’t just teach students general critical thinking; we also have a moral obligation to give them some tools so that they can come into the workforce ready.”

Mendoza knows from firsthand experience that mastering the science is only half the battle for many students from underrepresented backgrounds. He grew up in East LA where he learned how to reach across cultural divides from his Hispanic background to connect with others. “Learning to ‘go-between’ is a skill that’s essential for just having a community, and I think bringing that here made it really easy for me to understand when students are struggling,” Mendoza says. He asks himself questions like, How do you reach out to a student who’s not responding in a normal way? How do you make geology instruction more accessible? How do you engage students in the coursework? With this approach to teaching, Mendoza is able to connect with his students to enhance their experience and has earned multiple prior teaching awards in the process, including the National Association of Geoscience Teachers Outstanding TA Award, 2022.

Hidden curriculum

The obstacles for underrepresented students in academia don’t end after earning a bachelor’s; they just aren’t widely discussed. On top of regular classwork, first generation graduate students have to tackle the “hidden curriculum” within academia. This includes issues such as figuring out how to write a dissertation, what the college’s practices are, how to handle advisor conflict and other difficult-to-ask (and -answer) questions.

The overarching difficulty is determining what graduate school is supposed to look like in the first place, which Mendoza says is almost by design. “Grad school is very heterogeneous. Part of that is good because science looks different across disciplines, but that is [also] confusing for first gen grad students who don’t know how to navigate this unknown academic culture.” It’s a problem that is systemic, and not unique to the U.

To succeed in grad school, he says, “you can’t use the old paradigm, pushing boundaries like you did in undergrad and high school won’t necessarily result in the same success as a grad student. The cultural setting is different.” Even outside of academia, underrepresented scientists face many of these challenges. According to Mendoza, geoscience is the least diverse subfield of STEM. Nature Geoscience reported that the last 40 years has seen zero progress with respect to minority representation within geoscience. The United States Geological Survey has the poorest track record of minority employees of all the federal government agencies and is nearly half as diverse as the next ranked federal agency. The lack of diversity is mostly due to the niche nature of the discipline. Unlike, for example, computer science, there is a relatively finite employment pool. 

Kevin Mendoza has come a long way since his geology lessons with his grandmother’s Chihuahuan rocks, and it has informed the legacy he is now leaving with students familiar with the challenges he has faced. The teaching award is an acknowledgement that the paradigm can shift, that the Earth can move.

Sandra J. Bromley Scholarship

Providing a Role Model for New Generations

The Sandra J. Bromley scholarship is a full-tuition scholarship for undergraduate students in the College of Science. It provides in-state tuition, up to 15 credit hours per semester, for eight semesters which allows each recipient to complete their degree. The program, now celebrating its 10-year anniversary, is funded by the generosity of Ray Greer, BS’86, in Mathematics.

Each year, a freshman student is selected as a new Bromley scholar, and rolls into the program, while a senior student graduates. This unique model provides continuous funding to the students and allows the College of Science to assist and monitor the students as they progress through their academic program.

“The Bromley scholarship is extremely valuable because it can serve a student throughout their entire undergraduate career,” says Peter Trapa, dean of the College of Science. “The cumulative effect for the student is truly profound. Each year we see the incredible results.”

In addition, Greer and his wife, Jill, host the Bromley scholars at least once a year on campus. The informal luncheon allows the students to report on their progress and discuss any problems or concerns.

“I have had the pleasure of meeting and getting acquainted with the undergraduates as they progress through their academic goals, and it is always a pleasure to see their progression and academic interest flourish over time. In all I have done throughout my life, this has been one of the greatest and most rewarding experiences I have had the opportunity to be a part of,” says Greer.

Role Model

When Greer was just 12 years old, his mother, Sandra J. Bromley, moved her young family from Texas to Utah. The year was 1976. Bromley was promptly hired at the University of Utah and enjoyed a successful career as a technical illustrator in the College of Mines and Earth Sciences under the direction of Frank H. Brown.

“My mother was the single greatest influence in my life,” says Greer. “She taught me the value of hard work and perseverance. She also insisted that college was not optional. It was like going from junior high to high school — you just did it!”

Greer enrolled at the U for fall semester 1981 and was initially interested in computer science and engineering. However, computer science was highly competitive at the time so available classes were scarce.

“Fortunately, Hugo Rossi, a math professor, convinced me that if I majored in mathematics I could get as much course work in computer science as I wanted,” says Greer.

For several years Greer worked through the rigorous mathematics major requirements. He persevered and completed his math degree in 1986.

Then, in 2000, Greer’s mother moved back to Texas for the remaining years of her life. She passed away in 2011. Shortly thereafter, Greer established the Sandra J. Bromley scholarship to honor his mother by providing a way for deserving students to earn a college degree.

“She worked hard to provide for her family, but her greatest regret in life was not attending college herself, hence the vision behind the Bromley scholarship,” says Greer.

“Her requirement was that she would support me as long as I didn’t quit school,” says Greer.  “That is why the Bromley scholarship requires continuous attendance.”

Solving Problems

Greer has more than 40 years of experience in logistics and transportation industries. He has held senior management positions for Greatwide Logistics Services, Newgistics, Ryder Logistics and FedEx. He served as president of BNSF Logistics, headquartered near Dallas, Texas, from 2011 to 2018.

“Math allows me to think critically about situations and problems generally. Not just numerically but logically, to find patterns and trends that point to likely outcomes,” he says.

In 2018, Greer was named CEO of Omnitracs, a leading company in onboard technology for the transportation industry. Omnitracs is an international billion-dollar company that provides telematic devices and logistics to support drivers and their organizations to be compliant, safe and efficient.

“Math is universal and most importantly it teaches you discipline and persistence to work a problem until it is solved. That process of critical thinking and problem-solving has served me well throughout my entire career,” says Greer.

In 2021, Greer sold Omnitracs and transitioned to advisory board work as well as becoming an operating partner for Welsh, Carson, Anderson and Stowe, focused on supply chain technology investments.

Ray Greer has high hopes and expectations for today’s college students. His advice: “Connecting with people — not apps and cell phones — will differentiate you from the competition.”


The Bromley Scholars


Eliza Robert

“I love the entire vibe of the university”


Eliza Roberts is the most recent recipient of the Bromley scholarship. A freshman at the U, she is pursuing a degree in applied math and physics, with an emphasis in astronomy and astrophysics. Being awarded this scholarship has made Roberts’ experience at the U even more valuable. “It has truly allowed me to focus more on my classes, and even take classes that I wouldn’t have taken otherwise,” she says. “With the scholarship, I don’t have to worry about the financial aspects of college like I was fully intending to, which means that I can explore my passions and dedicate my time to learning.”

In addition to her hard work as a student, Roberts works as a math tutor in the TRIO office at the U. One of her proudest accomplishments is receiving her Girl Scout Gold award, for which she focused on creating a safe backyard space for adults with disabilities. 

Roberts lives in Salt Lake City and makes the most of her time at the U participating in LEAP classes, a year-long learning community for entering University students, and even discovering top-secret study and nap spots on campus. “I love the entire vibe of the university,” she says. “I feel safe, valued, and free. I have been able to explore myself more than I have in years, and it has helped me figure out who I want to be.”

Dannon Allred
“Space is simply beautiful”


Dannon Allred was awarded the Bromley Scholarship in 2021 and just completed his sophomore year at the U. A passionate learner, he is studying physics with an astronomy emphasis. “Ever since I’ve been interested in science, I’ve felt a pull towards physics and astronomy,” he says. “There’s just a lot in astronomy that spikes my curiosity, there’s a lot that’s unknown, and [outer] space is simply beautiful.”

The Bromley scholarship has given Allred the opportunity to experience college without any financial worries and has allowed him to focus more of his energy on his passion for astrophysics. “Obviously one of the most daunting things about college is paying for it, and that’s a lot of stress that most students have to deal with,” he says. “I would say that’s what’s most impactful about the Bromely scholarship because it allows me to go through college stress-free in that aspect.” 

On top of his astrophysics studies, Allred has been involved in several research projects on campus. “In my freshman year, I was part of Dr. Boehme’s … lab as part of the Science Research Initiative doing research on Organic Light-Emitting Diodes (OLEDs) using spintronics,” explains Allred. “This spring, I did an introductory research project analyzing the spectral emission features of the Sombrero Galaxy with Dr. Anil Seth” who specializes in astrophysics. 

Allred’s hope is to complete a graduate degree in the field as well. Not surprisingly, when he’s not busy studying stars and galaxies far, far away, he loves astrophotography, admiring the universe through the lens of his camera.   ~ Julia St. Andre


Michaela Fluck
“Proceeding Into the Wilderness”

Michaela Fluck works in the Zelikowsky Lab, which researches neural circuits that affect stress, fear, and social behavior. “I’ve always been interested in neurobiology, since I was a kid,” she states. “I’ve had family members who’ve had strokes and other brain injuries.”

A biology major with a psychology minor, Fluck says the study of abnormal psychology is also a passion of hers. “Seeing what can go wrong with the brain and what’s behind [it] …  is super interesting as well.”

Fluck was inspired to become a doctor by her patients at Primary Children’s Hospital, where she works as a phlebotomist. “I want to become an advocate for patients,” she says, “and help people work through the difficulties of medicine. Kids tend to hate procedures no matter what, so helping them work through the procedures is honestly one of the most rewarding things I’ve ever done.”

Her favorite class was organic chemistry. “Not a lot of pre-meds can say that,” she jokes. Fluck also loved taking an acting class at the U which relieved the stress of being a STEM student and harked back to her time as an actress in high school, especially her appearance in the the late Stephen Sondheim’s epic musical saga about daring to venture Into the Woods~ CJ Siebeneck


Keegan Benfield
Who knew I could do that?”

As a Bromley Scholar, Keegan Benfield BS’23, was able to spend more time on scientific passions, such as research and projects. “The Bromley Scholarship and the U have helped shape me to be the best that I can be.” 

Along with his double majors in mechanical engineering and physics, Benfield focuses his time on humanitarian efforts, volunteering with Youthlinc and Real life programs. He’s the president of the university’s marksmen club, and has attended National Collegiate events at the National and Junior level.

Prior to graduation, Benfield worked in the Deemyad Lab, researching condensed matter physics. The Lab focuses on theoretical physics, especially the physics of matter at extreme conditions of temperature and pressure.

One of Benfield’s favorite classes was Introduction to Relativity and Quantum Mechanics. “It was an ‘ah-ha!’ class that was challenging and fun,” Benfield says. “I have learned and expanded my knowledge in ways that amaze me. Who knew I could do that?”

Benfield recently completed a summer internship at Cosm and developed educational programs for planetariums using Digistar 7, which features full-dome programs and production services, giant screen films formatted for full-dome theaters, premium-quality projection domes, and theater design services. He plans on getting a master’s or PhD and work in a national laboratory or research company.   ~ CJ Seibeneck

Nobel winner Capecchi discovers new brain mechanism

The pandemic and its aftermath have raised anxiety to new levels. But the roots of anxiety-related conditions, including obsessive-compulsive spectrum disorder (OCSD), are still unclear.

In a new study, University of Utah Health scientists discovered insights into the importance of a minor cell type in the bra in — microglia —i n controlling anxiety-related behaviors in laboratory mice. Traditionally, neurons — the predominant brain cell type — are thought to control behavior.

The researchers showed that, like buttons on a game controller, specific microglia populations activate anxiety and OCSD behaviors while others dampen them. Further, microglia communicate with neurons to invoke the behaviors. The findings, published in Molecular Psychiatry, could eventually lead to new approaches for targeted therapies.

“A small amount of anxiety is good,” said Nobel Laureate Mario Capecchi, Ph.D., a distinguished professor of human genetics at the Spencer Fox Eccles School of Medicine at University of Utah and of biology in the School of Biological Sciences. He is also senior author of the study. “Anxiety motivates us, spurs us on, and gives us that extra bit of push that said, ‘I can.’ But a large dose of anxiety overwhelms us. We become mentally paralyzed, the heart beats faster, we sweat, and confusion settles in our minds.”

“This work is unique and has challenged the current dogma about the role of microglia function in the brain”

Capecchi, who arrived at the University of Utah in 1973 did much of his early research, leading to his Nobel Prize, at U Biology where a permanent display of his original equipment involving gene-targeting is housed.
