Four alumni have been honored as distinguished alumni for 2023 in the Department of Chemistry.

Zlatko Bačić:  Tectonic Science

“When two people limited to different ways of thinking come together, you have a synergy that couldn’t exist otherwise,” says Zlatko Bačić PhD’81, speaking on the vital importance of collaborating across the divisions of science. First-hand experience with this synergy is deeply embedded in his history, from serving as the inaugural director of the Simon Center for Computational Physical Chemistry to studying the quantum dynamics of molecules in Los Alamos

He compares the sciences to tectonic plates, constantly moving in varying directions, uncovering the most exciting discoveries where they collide at the edges. “It’s at those interfaces that the most interesting things happen!” he explains. And just as the Earth’s plates change the landscape, so too can the scientific landscape be terraformed in turn.

Bačić’s journey has not only taken him across the field of theoretical chemistry but across the world, studying everywhere from Croatia to Chicago to Jerusalem to Utah. He found a deep love of the culture and cuisine of New York and Philadelphia, while also delighting in the environment and people in the Four Corners area. He loves the town of Telluride,Colorado but also enjoys visiting his daughter in Seattle, creating a bewildering decision when considering a destination for a far-out retirement. He takes every opportunity he can to travel and experience every area to its fullest potential.

Bačić carries this attitude into his teaching as well. As a current professor at New York University, he has uplifted the lives of countless students and overseen the publication of over 150 papers. “Basic research is at the heart of everything,” he tells his students. “If you think you can guide it somehow, you’re missing the point. It is only unguided research that will illuminate the mysteries you know nothing about.” Championing the value of “unguided research,” he delights in providing opportunities for postdocs, creating an environment for them to prove their worth, opening every door for collaboration to let them show what they can do under optimal circumstances. ~ Michael Jacobsen

Amy Barrios: A world-class education

A Professor of Medicinal Chemistry in the College of Pharmacy, Amy Barrios’ passion for inorganic chemistry began at the University of Utah as a high schooler during a summer chemistry program and propelled her through a career in academia to Professor of Medicinal Chemistry in the U College of Pharmacy.

Barrios BS'95 grew up in Salt Lake City. During her time as an undergrad, she engaged in radiobiology research about Chernobyl victims with radiobiologist Scott Miller, now research professor emeritus at the U's School of Medicine.

Barrios ventured from Salt Lake to the East coast to earn her PhD in chemistry at the Massachusetts Institute of Technology in 2000. There, she dove deeper into bio-inorganic chemistry with Steve Leopard. “My focus was on making molecules that would mimic the activity of metalloenzymes. And I specifically looked at urease, which was actually the first enzyme ever discovered,” says Barrios. “I was making dinuclear nickel complexes that hydrolyzed urea.”

After graduate school, Barrios returned to the west coast and spent some time in California, first in a postdoctoral position at University of California, San Francisco, and later as a professor at University of Southern California.

Finally, Barrios returned home to the U in 2007, this time as a professor. Throughout her education and career, Barrios has visited many institutions and says she’s “...continually impressed by the quality of education that I got here at the U.”

“Our chemistry department, particularly, does an amazing job of educating undergraduates and graduate students, helping us understand all the things we need to know, all the tools we need to go on to be successful in whatever career we go into. So that's something I think is important for our students to recognize: they really get a world class education here.”

Barrios is keen to deliver a message of belonging as she continues in academia. “It's so important, I think, for students to be able to feel like they belong here,” she says. “We need scientists from all backgrounds and with all kinds of different interests and all kinds of different skills. So, I think that's really important also for young people to recognize and for us as faculty and instructors to help them feel that this is a place for them, that we need their talents, and their talents are valued. I hope that they get that message here.”

Roger Leach: lifelong learning and agility

Originally from Chicago, Roger Leach Phd'84 first journeyed to the University of Utah for a summer REU program while pursuing his undergraduate degree in chemistry from Augustana College in Illinois. The program allowed him to explore hands-on scientific research for the first time and, captivated by the unique outdoor access and balanced lifestyle he enjoyed in Salt Lake, City Leach returned to the U for graduate school.

Reflecting on his time here, Leach fondly remembers Joel Harris, a distinguished professor whose openly enthusiastic teaching style and love for science still inspire Leach today. “Everything about it was like, the door’s open, walk in, and let’s talk,’ he recalls. “My whole career after Utah, that was sort of my motto you know, ‘What would Joel do?’”

After finishing his graduate degree at the U, Leach began his career working as an analytical chemist in the textile fibers department at DuPont. Though he recalls the initial nerves he felt upon joining the company, Leach acknowledges the U for preparing him well: “[At Dupont], you could meet people who had really moved the bar in terms of technology development that made people’s lives better. So I felt intimidated a little bit, but there was never a time when I felt inferior in terms of my education and preparation.”

Since his days at DuPont, Leach’s career has led him to Viridos, a biotech company focused on algae-based biofuel. For the last few years, Leach has been helping to push the boundaries of renewable energy technology, hoping to create a more sustainable future. Currently a resident of Solana Beach, California, Leach emphasizes the importance of continuing to foster curiosity throughout his career: “The thing that strikes me is how many things we understand today and use today in our daily lives that didn't exist when I was at the University of Utah,” he remarks.

“And the process of keeping yourself relevant as a STEM contributor to society is an exercise in lifelong learning and agility.”
~Julia St. Andre


Mitch Johnson:  reinventing and modernizing formulations

Mitch Johnson first joined the University of Utah as a graduate student in 1994 after finishing his undergraduate degree from Concordia College in Moorhead, Minnesota. He knew he was interested in doing research and was drawn by the U’s outstanding research facilities and small university feel. During graduate school, Johnson worked in Joel Miller’s lab where he gained valuable skills in problem-solving and perseverance. “If I had like four or five ideas, Dr. Miller was very patient and listened to all of them,” Johnson recalls. “I learned that you have to put the work in. You really do have to spend the time and invest yourself completely into solving the problem.” 

For Johnson, chemistry truly runs in the family. His father, a chemical engineer, sparked his interest in the subject at a young age. Later, at the U, he met his wife, who was also pursuing a degree in chemistry. Their shared passion for the field often sparks discussion over dinner, and they even keep a whiteboard nearby for spontaneous problem-solving. Fascinated with creating things and solving problems, synthetic chemistry was the ideal path for Johnson. His career took him to General Plastics, developing specialized thermoplastic materials for use in aerospace engineering and satellite work. He started at the company in 2008 as a product development chemist, with the mission of reinventing and modernizing their formulations. Since then, the company has expanded significantly, and Johnson made his way through the ranks, eventually taking over the company as President and CEO in 2017. 

Looking back on his education, Johnson emphasizes the lasting impact of his time at the U: “The staff and faculty here are fantastic. They really do cultivate very good students and very well-trained professionals.” he says. “A lot of the success I’ve had over my career, it all started here at the U.”

Pete Johnson: An Abundant Source of Energy

Pete Johnson, An Abundant Source of Energy

Pete Johnson, BA’03 physics, is a source of boundless energy. At just 45, the husband and father of four has earned a master’s degree in mechanical engineering at Stanford, founded and built several leading companies, worked as a venture capitalist and investor in Silicon Valley, and is currently the president and CEO of Koloma, Inc., a global leader in geologic hydrogen exploration.

What focuses his energy, though, is his family — wife Kristin, daughter Sydney, 16; daughter Grace, 14; son Josh, 10; son Levi, 8.

Johnson is exploring and developing technologies to tap a new source of energy that is powerful, vast, and clean. It’s known as geologic hydrogen. Studies suggest that the earth produces significant amounts of hydrogen through natural geochemical processes and that it may be accumulating in formations below the surface. If sufficiently sized reservoirs can be found, geologic hydrogen could help fuel the U.S. economy for centuries to come while reducing emissions and carbon footprints.

Johnson grew up in The Avenues neighborhood of Salt Lake during the eighties. “I was born the fifth of six sons and had an unbelievably fun, Huck Finn-type of childhood exploring the foothills by foot and bike with my brothers,” he says. “We also spent a lot of time skiing, boating and going to high school sports games for my older brothers.”

At East High School, Pete was inspired by several teachers and classes, including AP Biology and AP Calculus. “I think the most inspiring person for me at East was Keeko Georgelas, the head coach who revitalized the school’s football program and took it from a perennial doormat to one of the top programs in the state. Keeko put into our heads that we could do great things.” Pete took those words to heart, channeling that motivation as he led the East High football team to a state championship in 1997, his senior year. It was the first championship at East since 1974.

Awarded a four-year presidential scholarship, Johnson enrolled at the University of Utah for Fall semester 1997 intending to be an environmental or civil engineering major. “I was interested in biology and math and wanted to be in the environmental remediation and hydrology world, in part thinking that it would give me lots of opportunities to work outside.”

Johnson completed the prerequisite courses before serving a two-year church mission. When he returned, in 2000, he struggled to find passion for the course work. He persisted and took a few more civil engineering classes but wasn’t intrigued with the subject matter.

“I started thinking about what else I could do and was in the middle of a general physics course taught by Sid Rudolph who was just a crazy man and unbelievably passionate about physics,” says Johnson. “I decided to give it a try and was pleasantly surprised with the curriculum and the way I was challenged by the science and the math.”

“I had tough, interesting courses in quantum physics, nuclear physics, electromagnetics and other areas from faculty [not only] Sid Rudolph, [but also] Clayton Williams, Mikhail Raikh and Rich Ingebretsen," says Johnson. "Rich was a longtime family friend who also taught me how to run rivers.” It was the cumulative effect of these courses, and perhaps hitting the rapids, that inspired Johnson to become an entrepreneur in the energy sector.

“My dad was in energy, and it was always something that I was interested in," says Johnson. "So, I applied to the mechanical engineering graduate programs at Stanford and MIT and was accepted into both programs."

Johnson chose Stanford and spent two years there, mostly doing biomechanical research where he found some fascinating topics in stem cell implantation into heart tissue. “At that point, it was time to propose a PhD project, but I struck out on two or three different ideas, being told by my advisor that these ideas sounded more like business plans than research projects. I kept trying to ‘science’-up the proposals but wasn’t getting it, and I realized, probably later than my advisor, that I was more interested in stepping out and pursuing things in Silicon Valley than I was in three-to-five more years in the lab. So, I finished with a master’s degree and never looked back.”

Modern day gold rush

The company name, Koloma, was inspired by the small town of Coloma, California, where gold ore was discovered in 1848 which led to the California Gold Rush that transformed the country and the entire economy. Johnson and company founders Tom Darrah, Paul Harraka and Scott McNally visited the site in 2021 to launch Koloma, Inc. Geologic hydrogen has also been referred to as gold hydrogen, so the team thought the name was appropriate. An appreciation for the history of exploration and the value of learning from the past is embedded in the company.

“The unique thing about Koloma is that we have 20 years of data advantage and a big head start in the field, and that data advantage has led to a large number of tools and techniques we can build and validate through our exploration work,” says Johnson.

Koloma has already developed the technology to identify the most promising regions for geologic hydrogen potential. The company continues to conduct geophysical studies and some preliminary drilling projects around the world. Johnson anticipates large-scale hydrogen production to begin by 2030 if they are successful in their exploration efforts.

As a new primary energy source, naturally occurring geologic hydrogen could be a powerful tool to help move towards lower carbon energy forms in the U.S. and around the world.

The Science

Geologic hydrogen is generated naturally in the Earth’s iron-rich mantel by an oxidation-reduction reaction known as serpentinization. Through this water-rock reaction, considerable quantities of hydrogen are continuously produced and stored in geological formations below the surface. In fact, geologic hydrogen can be produced with low-carbon intensity, resulting in a low-carbon footprint on par with electrolysis. In addition, the process does not require external water inputs or external energy inputs such as heat or electricity.

For these reasons, geologic hydrogen presents a highly efficient, low-cost and low-greenhouse-gas energy source.

Even with all that potential energy in development, Johnson’s internal energy source is rooted in Mountain View, California, near Stanford where he and his family reside.

“We’ve always got plenty going on,” says Johnson of his family which spends weekends at soccer games, hiking in the redwoods or hanging out on the Northern California coast.

He met his wife Kristin in September 2003, the first weekend he was in Palo Alto for graduate school. “Kristin had just taken a job with Pfizer in sales. I was smitten early on, but she was dating guys who didn’t have years of grad work in front of them and were already going places, so it took me about a year of building trust as a friend before she really started to see me as a viable option!”

“Once we started dating it was clear we had something great going on, and I think my mom would have killed me if I messed it up so I was careful,” says Johnson who proposed at sunrise on top of Half Dome in Yosemite National Park. They were married in October 2005 in Salt Lake City.

Pete Johnson’s advice to others is simple and, not surprisingly, family-centric: “Avoid thinking that being passionate about your work means you won’t be able to be a great spouse and parent. Find a way to make it all work.”

Ron Perla, 2024 Distinguished Alumnus

Avalanche Escape Artist


September 4, 2024

“I out-swam a size three avalanche down a gulley that had been artillery blasted,” reports Ron Perla to Wildsnow, a ski and snow reporting site. “It was my introduction to the post-control release.”

Recipient of the 2024 Distinguished Alumni award from the Department of Atmospheric Sciences, Perla graduated in 1971 with his PhD from the University of Utah in meteorology. As a snow scientist, he conducted research into avalanches and is well-known for discovering “the thirty-degree threshold,” where slopes of thirty degrees or more are much likelier to cause avalanches.

Perla worked at Alta Ski Resort as a member of the ski patrol and in 1966 became a part-time snow ranger and part-time research assistant at the U.S. Forest Service (USFS) Alta Avalanche Study Center. As a research assistant to Ed LaChapelle, Perla researched slab properties, factors that contribute to an avalanche and rescue methods, among other things.

Early in the morning and during intense storms, snow rangers blast the mountain to reduce the risk of avalanches. Between these times, Ed LaChapelle allowed Perla to take classes at the U. From 1967 to 1971 Perla commuted between Alta and the university. He split his time between snow rangering and his PhD program supervised by Professor Shih-Kung Kao and included classes in meteorology and applied mechanics. These classes are fundamental disciplines for avalanche research.

Perla’s advisor, along with the Department of Meteorology's chair Don Dickson, understood the unique combination of university study and avalanche study. Kao was a world-class specialist in atmospheric dynamics, turbulence and diffusion while Dickson was a highly decorated World War II pilot with hands-on meteorology experience. He helped Perla obtain a research grant from the Rockefeller Foundation and arranged for the donation of an old Alta ski lifts building which was turned into a mountain meteorology lab.

Models of moving avalanches

Perla has also extensively researched snow structure as well as models of moving avalanches. His current research involves quasi-three-dimensional modeling of the internal structure of a moving avalanche, from start to stop and has modeled moving snow in many different ways. His first model (1980) followed the mass-center of moving snow, and in 1984 his model assumed the avalanche as a collection of starting particles. The current model assumes the avalanche consists of snow parcels moving turbulently in three layers.

Ron Perla, U.S. Forest Service, 1968.

Along with his research, Perla has spent a lifetime in the snow. An avid skier and mountaineer, he partnered with Tom Spencer (U alum in mathematics) in 1961 for the first ascent of Emperor Ridge on Mt. Robson, the highest point in the Canadian Rockies. He also established a new route on the north face of the Grand Teton in Wyoming and a first ascent of the popular “Open Book” route on Lone Peak in the Wasatch Mountains.

“In 1967, I was working as a USFS Snow Ranger near the top of Mt. Baldy,” Perla says. “The cornice broke off prematurely, and I fell into a Baldy chute. The cornice blocks triggered a large avalanche. I was tumbled around with no chance of 'swimming,' and somehow I missed all of the rocks. Just before I lost consciousness under the snow, I managed to thrust an arm up to the surface. I was found quickly.”

Collective consciousness

Perla is an honorary member of the American Avalanche Association as well as a member of multiple different snow and ice committees, such as the Snow, Ice, and Permafrost committee for the American Geophysical Union.

After earning his PhD at the U, Perla moved to Fort Collins, Colorado as a research meteorologist for the USFS. In 1974, he moved to Alberta, Canada to work for the National Hydrology Research Institute. He has remained in Alberta since.

Perla is a significant reason why we understand snow science and avalanches and why backcountry education has improved to help keep those who recreate in areas with snowfall — skiers, mountaineers, snowshoers and ice climbers — safe.

“Despite the enormous increase in backcountry use, despite increasing behavior to ski and ride lines we could never imagine in the 1960s, avalanche fatalities are not increasing to match those trends,” Perla says in an interview with Wildsnow. "Surely, associations, centers, websites, and educators, in general, are responding to match those trends. Surely it’s also because today’s risk-takers are increasingly more skillful backcountry skiers, riders, and [,as in Perla's harrowing experience on Mt. Baldly,] escape artists."

He continues, adding that "[e]quipment is improving. ...But there’s something else: call it collective consciousness in the backcountry. An increasing number of backcountry users correlates with increasing observations and tests. Thus, safety can be enhanced by numbers if there is increased communication... ."

Earnshaw joins Tim Hawkes, attorney and former Utah legislator, who was announced as the inaugural senior fellow in 2023. The College of Science senior fellows represent a variety of industries and provide key insights and guidance to leadership and faculty.

 

 

Life On Other Planets … and in a student’s mind

Life On Other Planets … and in a student’s mind


June 13, 2024
Above: Mary Fairbanks BS'23, biology

A DNA repair system known as the GO DNA repair system removes oxidized guanine. This helps protect the system from mutating, and while scientists understand how it works, the origin of this mechanism isn’t well understood.

That’s where the Martin Horvath Lab comes in and, in particular, Mary Fairbanks BS’23. She and her team in the School of Biological Sciences at the University of Utah explore structural biology and biochemistry by researching microbes from the Lost City Hydrothermal Field, an area of marine alkaline hydrothermal vents located in the Atlantic Ocean. 

As with Fairbanks, who gained hands-on experience creating experiments and directly participating in research, other lab members worked on the project as undergraduates before graduating. They include Payton Utzman BS’22 and Briggs Miller BS’22 who along with Fairbanks and graduate student Vincent Mays researched microbes that live at the bottom of the ocean where there is little oxygen and even less sunlight. Because of the lack of oxygen in the environment where these microbes thrive, the fact that researchers found GO DNA repair genes is important: it shows a need for genes that repair DNA that has been put under stress from oxygen. Their research was recently published in PLOS

Acting like a scientist

"Working in Dr. Horvath’s lab has taught me how to be curious and be dedicated to a project,” says Fairbanks. “Being able to design my own experiments has given me the opportunity to act as a scientist. I have grown through research and it continues to expand my view of the possibilities of innovation.” 

Horvath first learned that one of the GO repair genes called MutY might be present at the Lost City Hydrothermal Field from a student in his Molecular Biology of DNA Lab course, Emily Dart HBS’16. Horvath knew that Dart was working with William Brazelton, a fellow biologist who had recently collected DNA from Lost City. Searching that Lost City DNA, Dart and her teammates found genes encoding at least portions of MutY.

“Since that first analysis,” says Horvath, “the sequence technology improved, more samples from another expedition generated metagenomes with better coverage, and we now have functional tests that show these MutYs from the bottom of the ocean actually work to prevent mutations in lab strains of bacteria.” That these discoveries stemmed from basic science research by undergraduates, he says, is “something that I am very proud to celebrate!”

How life might evolve on other planets

GO DNA repair genes are advantageous even in environments without much oxygen. Since hydrothermal fields like the Lost City Hydrothermal Field are similar to the environment of early Earth, this indicates that these repair systems evolved before the Great Oxidation Event.

Fig 5. LCHF MutY chemical motifs. (A) Conservation and diversity of MutY-defining chemical motifs are depicted with a sequence logo for the 160 LCHF MutYs. These motifs are associated with biochemical functions including DNA binding, enzyme catalysis, attachment of the iron-sulfur cofactor, and recognition of the damaged OG base.

Insights like this can help develop models of how life might evolve on other planets. Planets that lack the abundance of oxygen that modern Earth has may have life evolving in a similar way to microbes that live near hydrothermal vents. Since these microbes have repair systems that deal with oxidative stress, it’s reasonable to consider that life on other planets may as well.

The group also discovered the role that these repair genes, including MutY, play in hydrothermal microbes, by associating GO DNA repair with metabolic pathways. These pathways produce oxygen as a byproduct, so MutY may play a part in fixing DNA damage caused by metabolic processes.      

Life on other planets may take many different forms, and similarly, learning science also takes many forms beyond the classroom. “I’ve been encouraged to ask questions and explain findings to form a cohesive pattern that tells a story,” says Fairbanks. She credits the lab experience as helping her “see a project from start to finish. I have been able to improve my critical thinking skills and laboratory technique, as well as adapt to change.” 

That adaptation to change is a good lesson to learn as empirically observed far below the surface of the ocean but also on a personal level for Fairbanks and her young researcher cohorts. Findings such as these may show how DNA-based life forms rely on fixing damage caused by oxidation, even in environments without oxygen. And they give scientists a clue as to how life may look on other planets by forming models of life in environments unlike Earth’s. But the “findings” are clearly internal as well for young, developing scientists who will never forget their time examining and interpreting data in the Horvath Lab. 

As Martin Horvath intones of this research, “Life finds a way.” 

As do young minds like that found embodied in Mary Fairbanks who, now headed for a career in the medical field, concludes, “I believe my experience in research will make me a more open-minded thinker.”

As an undergraduate, Yassmin completed a double major in quantitative analysis of markets and organizations (QAMO) and mathematics with an emphasis in statistics. This spring he graduated with a master's in statistics.

Balancing football and academics was challenging, but Yassmin performed this balancing act well, earning a spot on the PAC-12 Academic Honor Roll multiple times during his five years at the U.

Yassmin has advice for other students balancing busy schedules: "You've just got to prioritize certain things. There are a lot of sacrifices that have to be made. Sometimes weekends are just not the weekends you want to have, or your friends ask you to come over and you just have to suck it up and put your head down for a couple hours and get your work done first before you do anything else. Little things add up, an hour here, an hour there, dedicating times where it's undistracted work. By the end of the week, it accumulates. I think that's the thing, just sacrificing certain amounts of time to make sure you get your stuff done first."

Yassmin was fortunate to have had some stellar professors, especially Lajos Horvath, from whom he took multiple classes, and Tom Alberts, his project advisor. They understood his unique position and helped him navigate the balancing act between athletics and math. Yassmin expressed that he probably wouldn't have made it through his MStat degree without them.

“The work I’ve done both within and outside of the mining industry has helped me understand what the outside community thinks about mining,” says Denee Hayes BSME’02. She explains that there is a misunderstanding about how mining contributes to green energy, sustainability and the environment. Through her diverse work experience, she developed the talking points and negotiating skills to be a moderator and mediator between mining and environmental groups. “It really shaped the work that I’m doing today in mining, manufacturing as well as utilities and other sectors.”  

While not on the trajectory of the late Loretta Lynn, whose 1971 Grammy-winning song “Coal Miner’s Daughter (and later, the Academy Award-winning bio-pic starring Sissy Spacek) told the story of the country singer’s upbringing in Butcher Hollow, Kentucky and her elevation into stardom, Hayes’ journey is no less auspicious. In fact, Hayes’ career may end up having a profound impact on the defining issues of our times. Arguably, it already has.  

Hayes was raised in Farmington, NM by parents who owned an oil and gas business. Her father was from Carbon County, Utah and not only worked in oil and gas as well as in mining sales. He also drove a truck for the coal mines in Wyoming. Both of her grandfathers also worked in oil/gas, construction and mining in Utah, New Mexico, and Arizona. Even before high school graduation, Hayes showed an interest in getting a degree in mining engineering. Poised to swoop in, the University of Utah offered a full-ride scholarship and, critically, the industry offered internships and industry experiences starting the summer before she arrived on campus in 1994.  

 

Thought leader 

Since graduation in 2002 Hayes has become a thought leader in the necessary convergence of mining and the new green economy. This, while working for nine years in-house with Utah’s Kennecott Copper until 2020 when she pivoted to private consulting, which she continues to this day.  On the academic side, she was the first woman chair of the Mining Engineering department’s industrial advisory board. 

 The stakes right now in reimagining the mining sector as it relates to a green economy could not be higher. Regarding the climate challenge at large, we really only have one chance to get it right, according to New York Times David Wallace-Wells. In a recent Tanner Humanities Lecture at the U, the climate journalist reported that half of all carbon emissions have come about in just the last 25 years. Even more startling, the weight of that carbon (yes, there are methods of measuring it), is more than the total mass of everything ever built by humans and still standing on earth.  

 Hayes and her colleagues and collaborators may well be up to the herculean task as they look more closely at the complexity of the mining/environment conundrum, and to find allies. “I like the ability to pull together — the interdisciplinary approach — to solving these problems and issues,” she says.  “Diversity of thought and mining engineering gave me the technical knowledge and the language to work between the parties.” She views her training at the U as forging her into a “jack of all trades,” earning a degree that crosses various kinds of engineering — mechanical, civil, electrical — with the pure sciences of physics, chemistry and high-level mathematics. This interdisciplinary approach has threaded through her training and work experience via software development, utilities, manufacturing, architecture, mining engineering, integrated operations, and corporate leadership, all while deploying her signature bridge-building skills.  

 The span between mining and the environmental ethic is not a small one, and it is by dint of Hayes’ experience in a variety of sectors that she has forged her current work as a consultant. “The work I think I did [at Kennecott and elsewhere] gave me a view of two sides, really seeing how the industry has a PR problem and that mining [professionals] have really pitted themselves against environmentalists and other industries, and how we really need to show that if you are pro-green energy you have to be pro-mining.”  

At first blush, such a statement seems counterintuitive, but she continues. “If you think about the trajectory society is currently on “there are ebbs and flows in everything for green energy” whether it’s photovoltaic materials to convert sunlight into electric energy or other sources of renewable energy, like wind and hydro power.  

The greening of America 

To keep up with green economy demands, Hayes explains that the world “will need to mine the same amount of copper between now and 2030/40 as we have in all of humanity,” And that is an example of just one metal. “Because there’s that much copper that goes into those things [i.e., green technologies, coupled] with population growth, even power transmission — from coal or a green energy source —  you still utilize copper and a whole host of other critical minerals within that energy transmission and distribution.”   

Do you rely on a mobile phone? Hayes is quick to remind us that more than half of the periodical table goes into producing and running your cell phone. Furthermore, “anything in the periodic table needs to be mined.” 

The challenge of greening America is not just about extraction of critical metals from new as well as historical mines (known as brownfield sites) which are being re-opened and are using new technologies to re-mine, for example, tailings. It’s also about water use, of particular concern to those of us in the West. Part of building a consensus between two opposing sides is to hold a space for both without papering over reality, on either side.  

“I think that we now have an opportunity to right some of the wrongs of mining in the past and some of the ways that we didn’t understand how we were harming the Earth,” she says, not only referencing Environmental Protection Agency-designated superfund sites of mines but seeing the sector from the view of digital optimization of the entire value chain. These involve standards, both enforced by governmental regulations as well as industry best practices that don’t exist outside the U.S. which is why Americans have relied on questionable extraction services outside the country, something that Hayes finds unacceptable. “If we want to continue leading the lives we are leading, we have to do our own extraction operations of critical materials ethically.” 

Ethical practices extend as well to current mining employees and can only add to efficiencies that stakeholders demand. Hayes values “helping connect the executive level strategy to the front line, figuring out how to get the front line activated to enact that strategy.” In other words, it's not just about getting employee “buy-in” but demonstrating the “how,” to all of them — operators, maintainers, samplers and surveyors on site — of deploying lofty executive team decisions. “You’re leading people and focused on their safety and well-being and not just managing the tasks at hand,” she says.  

It's all part of Hayes’ “holistic” approach to the issues, of thinking outside the blast hole, as it were, and through the “muck” (a general term in the industry of blasted rock that is ready to be loaded). A thoughtful intervention characterized by the belief that the parts of something are interconnected and can be explained only by reference to the whole is how “defining problems” of our age get solved . . . or at least managed.   

Moving the needle 

In the field.

And clearly for Hayes, it’s not just about operations, safety and profit — or even of financial stakeholders for that matter. It’s about moving the needle in the industry towards not only a greener way of doing things, but a more just and equitable way of doing those things as well.  

 The systemic reimagining of mining is a daunting proposition, and it requires bringing in diverse voices to inform, what Hayes calls, the “broader topics of that broader conversation.” She well remembers being an undergraduate — one of only three or four women in the department. That hasn’t changed much in the last 30 years with most mining organizations reporting only 7-10 percent of a work force made up of women.  

 “The real work needs to be for everyone to understand that a career in mining is a career for the environment, for green energy, and having that will be an attraction for people to come in. [We need to] make it psychologically safe to work in this industry, which it hasn’t always been. It’s work that we all have to do . . . .When you’re trying to tackle these large problems in industry you really need the diversity of thought that comes out of these different mining programs.”  

 The U’s program is no different. As with other institutions of higher education, its metrics of success are research, funding, student enrollment, and student success. “Industry needs to do its part to help create a pipeline of students to the U as well as look to the university to do some of their important research.” “The same holds true in reverse, universities need to be asking industry what will be most impactful for mining of the future.” If things don’t change, mining engineering departments across the country like the U’s will dwindle and die. “We’ve seen that in West Virginia,” she says, referencing beleaguered West Virginia University. In August the flagship Morgantown campus proposed eliminating nine percent of the majors and seven percent of its full-time faculty members.  

Critical materials, critical thought 

Fewer and fewer programs in all academic fields means less and less diversity of thought, which is critically needed. Hayes intends to advocate for better associations between industry and the university for this very reason. It’s a personally held mission that might have not only a macro difference but a micro one as well in these challenging times. She and her husband are the proud parents of another proverbial “miner’s daughter,” and her daughter is likely to be better positioned to consider a degree and a career in mining engineering because of her mother’s continuing hard work in the sector.  

When Denee Hayes recently won an honorary alumna award at the department’s most recent awards ceremony, the coal miner’s daughter had her dad in the room. “He was ecstatic to come and see me.” she says with a smile.

Solving Water Shortages by Lease

Solving Water shortages Through Lease

 

Booming growth is driving more demand for water, but climate change, aridification and an over-allocated system ensure a short supply.

State lawmakers have looked to farmers to solve Utah’s mounting water issues, hoping they’ll lease water to save the Colorado River and Great Salt Lake.

So far, almost no irrigators have signed up. Their reasons vary, but a pilot program on central Utah’s Price River shows farmers are willing to lease their water if it makes economic sense and if they trust the process. And the state has a lot of hurdles to overcome before water leasing makes a measurable difference.

“If we can generate the revenue we need with water versus putting something in the ground, it works,” said Kevin Cotner, a hay farmer near Price. “It’s yet another cash crop.”

Cotner just wrapped up his third season participating in the Upper Colorado Basin Commission’s water leasing project, called the System Conservation Pilot Program. He irrigated 450 acres this year and left 530 acres fallow. He got paid up to $650 per acre-foot left in-stream.

But Cotner’s participation in the pilot water leasing plan isn’t purely based on economics.

“This is a hard ag area to make a living. Things are pretty severe,” he said. “We’re transforming the desert. Water is one of the big issues.”

Cotner serves as the president of the Carbon Canal Co., and policing use is part of his daily life.

“I’m the bad cop,” he said. “I’m the water guy.”

Even after Utah saw record-breaking snowpack and runoff last winter, Cotner said drought is becoming the norm rather than an exception. Last year, his canal company could only deliver shareholders 38% of the water they’re entitled to on paper.

“That was a hard summer,” he said. “A lot of unhappy people.”

Booming growth in the West is driving more demand for water, but human-fueled climate change, aridification and an over-allocated system have ensured it remains in short supply.

The water leasing pilot is one strategy Upper Basin states identified to get demand back in sync with reality in the Colorado River system.

All the water Cotner conserved by fallowing his fields stayed in the Carbon Canal, making its way back to the Price River, eventually flowing to the Colorado River and Lake Powell reservoir. It will then flow to thirsty Lower Basin states like Arizona and California, helping the Upper Basin fulfill its obligations under the century-old Colorado River Compact.

At least that’s how it’s supposed to work. As of now, Utah and other Upper Basin states don’t have the ability to track where the saved water goes, or ensure another irrigator downstream doesn’t divert it away.

“We want to get there,” said Lily Bosworth, a U alumna from geology & geophysics and now a staff engineer with the Colorado River Authority of Utah. “That’s our goal.”
