How statistical physics illuminates sea ice

How statistical physics illuminates sea ice

Since he began studying polar sea ice at NASA in 1975, mathematician Ken Golden has helped document alarming changes in the seasonally shifting, thin veneers covering the Arctic and Antarctic oceans.

There’s now a lot less ice and the University of Utah scientist has since devoted much of his career to applying statistical mechanics—the physics of phase transitions and complex collective behavior in systems like gases and magnets—to better understand the role of climate change in the disappearance of our polar sea ice covers. The stakes couldn’t be higher as the impacts accelerate. In recent decades, according to Golden, the extent of Arctic sea ice has shrunk by about half.

“Not over the past million years, like on geophysical scales, not over a thousand years, but over the past 30 or 40 years. A couple of months ago, even in Antarctica, we just saw a new record low,” Golden said in his opening remarks at the May 17 Climate Summit hosted by the U College of Science’s Wilkes Center for Climate Science & Policy. “But just like throwing a rock into a pond, there are ripple effects, and the bigger the rock, the bigger the ripples and the further they go. The extent of sea ice we’ve lost in the Arctic is about two-thirds the area of the contiguous United States and is probably the largest change on Earth’s surface due to planetary warming. That’s a big rock.”

The part of Earth’s climate system featuring snow and ice, known as the cryosphere, is experiencing severe disruptions as the planet continues warming. Ice still covers 9% to 15% of Earth’s ocean surface, but the trends are ominous.

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.”

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.

Sandra J. Bromley Scholarship

 

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

The SRI puts students in a lab to do research as soon as they arrive on campus. After Eliza was admitted to the program, she began working with Fred Adler, professor of mathematics and of biology in the Department of Mathematics and in the School of Biological Sciences. "Math and physics have both had a special place in my heart for most of my life. Even back in elementary school, math and science always held my attention more than other subjects. I began to actively study physics in middle school and never looked back."

Following graduation she hopes to pursue a Ph.D. in theoretical astrophysics to use innovative computational and analytical techniques to better understand the dynamical processes at play on all scales of the cosmos.You can read an interview of Eliza here.

 

Audrey Glende
Physics & Astronomy
Mathematics
Philosophy of Science

An honors student with a triple major, Audrey Glende is currently researching a crystal and mapping its electrical and magnetic properties at extreme conditions, such as pressures similar to that of the earth's core temperatures just above absolute zero. The crystal (EuCd2P2) has been labeled as a superconductive candidate among other characteristics. As with electronic parts or materials used in fuel/battery cells, "many of the materials with complex properties," she says, referring to her work with the crystal, "are discovered through both theory and experimentation within condensed matter physics." It is this area of inquiry in which her ambition lies, and she is hoping to complete a Ph.D. in physics  and eventually share her knowledge through teaching at the college level.

Among many influential family members in her life,  she says, "I probably see myself most in my dad and know that it is very much so because of him that I have been comfortably hand-held into my passion for STEM in a way many people aren’t." Her father encouraged her to participate in science fairs as a youth and she was eventually recognized by Business Insider as having conducted one of the 30 most impressive science fair projects in the U.S. in 2015. Glende's faculty mentor is Professor Shanti Deemyad.

 

Daniel Koizumi
Mathematics

After graduation, "I hope to pursue a Ph.D. in Mathematics [and] conduct research in pure mathematics and teach at university," says Daniel Koizumi. His faculty mentors include Professor Karim Adiprasito, a German mathematician working at the University of Copenhagen and the Hebrew University of Jerusalem who works in combinatorics; Professor Sean Howe, who works in arithmetic and algebraic geometry, representation theory, and number theory; and Professor Jon Chaika, whose research in the field of dynamical systems seeks to understand a space and a map by following individual points.

Recipient of the departmental Undergraduate Award for Excellence in Graduate Courses, Koizumi's  ambition is to continue doing research at the intersection of combinatorial topology and commutative algebra. He spent three months in 2022 as a research fellow at The Hebrew University of Jerusalem. "On a lazy Saturday," he says, "I ... enjoy hiking, cooking, or running."

 

Nichols Crawford Taylor
Applied Mathematics Computer Engineering
Computer Science

"I love robotics, autonomous systems, and all the math and engineering surrounding them," says Nichols Crawford Taylor. "I'm excited for the future they'll create!" Taylor, a triple major, plans on pursuing a Ph.D. in robotics and then transferring to industry to teach and present his research.

"Right now," he says, "I’m working on skill sequencing for autonomous manipulation using partial views of objects. We don’t expect robots to have all encompassing knowledge, so we’re using human-like views of objects with color and depth. From there, my research is about how to put together different skills the robot has to achieve a goal, like re-arranging books on a shelf."

A presidential intern during the 2021-2022 academic year and, currently, the Residence Hall Association President at the U, Taylor has been on the Dean's List and is a member of Pi Mu Epsilon. He is also a member of the Jiu Jitsu club. His faculty mentors include Dr. Daniel Drew, Dr. Alan Kuntz and Dr. Tucker Hermans, the latter of whom he considers his hero. "His breadth of knowledge and experience is astounding," says the Orem native. "He knows so much about and surrounding the field, and has incredible insights on problems take a good bit of time to wrap my head around."

 

A.A.U. Membership

UTAH JOINS THE A.A.U.


 

"It is difficult to overstate the importance of AAU Membership. This elevates the U to an exceptional category of peer institutions."
- Dean Peter Trapa

 

The University of Utah is one of the newest members of the prestigious Association of American Universities, which for more than 100 years has recognized the most outstanding academic institutions in the nation.

Mary Sue Coleman, president of the Association of American Universities (AAU), announced Wednesday that University of Utah President Ruth V. Watkins has accepted an invitation to join the association, along with the University of California, Santa Cruz and Dartmouth College. The three new members bring the number of AAU institutions to 65.

AAU invitations are infrequent; this year’s invitations are the first since 2012.

 

 

“AAU’s membership is limited to institutions at the forefront of scientific inquiry and educational excellence,” said Coleman. “These world-class institutions are a welcome addition, and we look forward to working with them as we continue to shape policy for higher education, science, and innovation.” - Mary Sue Coleman

 

About the AAU
The AAU formed in 1900 to promote and raise standards for university research and education. Today its mission is to “provide a forum for the development and implementation of institutional and national policies promoting strong programs of academic research and scholarship and undergraduate, graduate and professional education.”

A current list of member institutions can be found here. The membership criteria are based on a university’s research funding (the U reached a milestone of $547 million in research funding in FY2019); the proportion of faculty elected to the National Academies of Science, Engineering and Medicine; the impact of research and scholarship; and student outcomes. The U has 21 National Academies members, with some elected to more than one academy.

An AAU committee periodically reviews universities and recommends them to the full association for membership, where a three-fourths vote is required to confirm the invitation.

Leaders of AAU member universities meet to discuss common challenges and future directions in higher education. The U’s leaders will now join those meetings, which include the leaders of all the top 10 and 56 of the top 100 universities in the United States.

 

“We already knew that the U was one of the jewels of Utah and of the Intermountain West. This invitation shows that we are one of the jewels of the entire nation.” - H. David Burton

 

U on the rise
In FY2019 the U celebrated a historic high of $547 million in sponsored project funding, covering a wide range of research activities. These prestigious awards from organizations such as the U.S. Department of Energy, National Institutes of Health and National Science Foundation are supporting work in geothermal energy, cross-cutting, interdisciplinary approaches to research that challenge existing paradigms and effects of cannabinoids on pain management.

They also are funding educational research programs with significant community engagement, such as the U’s STEM Ambassador Program and the Genetic Science Learning Center’s participation in the All of Us Research Program.

“AAU is a confirmation of the quality and caliber of our faculty and the innovative work they are doing to advance knowledge and address grand societal challenges. Our students and our community will be the ultimate beneficiaries of these endeavors. " - President Ruth Watkins

 

On Nov. 4, 2019, the U announced a $150 million gift, the largest single-project donation in its history, to establish the Huntsman Mental Health Institute. These gifts and awards are in addition to the ongoing support of the U from the Utah State Legislature.

This fall the university welcomed its most academically prepared class of first-year students. The freshman cohort includes 4,249 students boasting an impressive 3.66 average high school GPA and an average ACT composite score of 25.8. The incoming class also brings more diversity to campus with both a 54% increase in international students and more bilingual students than the previous year’s freshman class. Among our freshmen who are U.S. citizens, 30% are students of color.

The U’s focus on student success has led to an increased six-year graduation rate, which now sits at 70%—well above the national average for four-year schools. The rate has jumped 19 percentage points over the past decade, making it one of only two public higher education research institutions to achieve this success.

Anna Tang

Anna Tang


The Key in our Collective Hand.

"Mathematics,” says Anna Tang, “is a key in our hands that is able to change shape to fit almost any lock in the world.” A senior in math at the U, Tang not only uses that key to model how breast cancer tumors continue to grow despite estrogen controls in current therapies, but to apply for a Fulbright fellowship. In April, she was confirmed as a finalist and will be heading to Germany this fall.

A member of the Fred Adler lab known for its broad range of mathematical modeling work—from rhinoviruses to ant colonies and from sea ice to urban ecosystems–Tang is clearly enamored with math-biology models, which have grown exponentially, especially as they relate to healthcare applications. That interest not only stems from working on differential equations as a precocious youth–and now at the U. There was support from her parents: her mother, a research faculty member at U Health who was quick to instill in her daughter that failure is just one step toward success; and her father, a computer scientist. That her parents are both immigrants from post-communist China, and “not fluent in the language of elementary writing assignments,” they focused with their daughter on the universal language of math.

It turns out that another Chinese immigrant whom Tang refers to as “Auntie” propelled Tang even further into the language of math and its potential applications to healthcare. While working on her PhD at the U, says Tang, “Auntie took care of me when my mother [working as a post-doctoral researcher] and father were attending conferences.” Already an MD, Anna’s surrogate mom often told stories of working in emergency rooms in China. Then, in 2008, eight-year-old Tang traveled to Jiangxi Province to visit her Auntie who had earlier returned to China where she eventually learned she had contracted stomach cancer.

“She had always been so full of life,” recalls Tang, “helping others as a doctor and researcher … .” But now, the woman who with her mother was “pushing the boundaries of our knowledge … was decimated by the cancer that had affected her.”

While the experience with Auntie in China was fourteen years ago, Tang vividly remembers how bleak the woman’s hospital room was “except for one single, solitary sunflower in the vase next to her bed.” While looking at that flower and its seeds the third grader suddenly remembered, of all things, the Fibonacci Sequence–the series of numbers in which the next number is found by adding up the two numbers before it–and how it is found in nature.

That experience was “the root of the wish to apply math to life,” she says. There with her Auntie, Tang remembers wishing she could cure cancer “like you could solve a math problem. … Cancer is a strange land. It whisks its patients away to another world of fear and uncertainty.”

Unfortunately, the intrepid model to Tang of what it means to seek scientific understanding did not return from that land.

An honors student with a minor in chemistry, Tang will work with Anna Marciniak, a mathematical oncologist at Heidelberg University in Germany. In that lab Tang will be working to quantify the mutational landscape of another kind of cancer: acute myeloid leukemia. Using integro-differential equations she and her team will be asking what the mutations of cancer cell populations look like and how they present themselves phenotypically.

Meanwhile, Tang, who works as a TA in the Department of Chemistry, is readying for graduation later this year. She says that Adler, who is also Director of the School of Biological Sciences, “is the most eccentric professor I’ve ever worked with. In a good way,” she quips, then laughs: “He has in his office a list of ‘trigger’ things that he doesn’t want to see in a math model.” The Adler lab is a very collaborative environment, she continues, “always a blast! The projects are so diverse you get to see so many applications of math. It’s inspiring.” In the lab Tang works closely with post doc Linh Huynh, designing models, running simulations, collecting data and talking over fixed point stability and long-term behavior.

It's not every third grader who resonates with the Fibonacci Sequence. In fact, Tang finds doing mathematics, in a way, meditative. “I really love it because you’re just thinking. It feels a little like I can take myself away from technology just working with a piece of paper.” Reflexively, however, Anna Tang recalls her Auntie in that hospital room, and the Fulbright aspirant knows she wants to move through that heady, calming space, into simulations and eventually applications to healthcare.

“If there is anything that can prolong the life of a cancer patient,” she says, “it will be math,” the shape-shifting key in our collective hand that can fit most any lock.

McMinn Chair

Trevor James McMinn Chair


Christopher Hacon

Christopher Hacon appointed to McMinn Chair in Mathematics

On July 1, 2022, University of Utah President Taylor Randall appointed Distinguished Professor Christopher Hacon as the Trevor James McMinn Professor in the Department of Mathematics. Hacon held the inaugural McMinn Chair for five years—that term ended last June.

According to the terms of the appointment, this is a five-year appointment. Only one faculty member in the department may hold the appointment of the McMinn Chair at a time—in exceptional cases, the current Professorship holder may be considered for reappointment after a review has been conducted pursuant to the university’s policies and procedures for professorship holders.

Davar Khoshnevisan Chair of the Dept of Mathematics

“Distinguished Professor Hacon's work has been groundbreaking, and he is recognized internationally as a mathematical scientist of the highest caliber, whose work has motivated and impacted the next generation of brilliant algebraic geometers.”

 

Born in England and raised in Italy, Hacon arrived at the U as a postdoctoral scholar in 1998 and came back as a professor in 2002. He is particularly interested in objects that exist in more than three dimensions. He and his colleagues have applied studies of these objects to extend the “minimal model program”—a foundational principle of algebraic geometry—into higher dimensions. The American Mathematical Society has lauded their work as “a watershed in algebraic geometry.”
