Hanfeng Li named UB Distinguished Professor

Hanfeng Li has been named UB Distinguished Professor. His primary research interest is noncommutative geometry and dynamical systems, particularly connections between operator algebras and dynamical systems. A 2020 fellow of the American Mathematical Society (AMS), his recent work concentrates on actions of countable sofic groups and algebraic actions of general countable (amenable) groups.

Three faculty members have been named UB Distinguished Professors.

The UB Distinguished Professor designation — not to be confused with the SUNY Distinguished Professor designation, a rank above that of full professor awarded by the SUNY trustees — was created by the Office of the Provost to recognize full professors who have achieved national or international recognition as experts in their fields of study.

UB Distinguished Professors are members of the faculty who have been full professors for a minimum of five years with a demonstrated record of excellence in artistic or scholarly contributions.

This year’s honorees are Hanfeng Li, Erik Seeman and Sarah Xin Zhang.

Hanfeng Li.

Hanfeng Li is a professor in the Department of Mathematics, College of Arts and Sciences.

His primary research interest is noncommutative geometry and dynamical systems, particularly connections between operator algebras and dynamical systems. His recent work concentrates on actions of countable sofic groups and algebraic actions of general countable (amenable) groups.

In 2020, he was named a fellow of the American Mathematical Society (AMS) for his contributions to algebraic dynamics and operator algebras. He is the co-author of the 2017 book “Ergodic Theory: Independence and Dichotomies,” which introduces the ergodic theory and topological dynamics of actions of countable groups.

He has also received the UB Exceptional Scholar Sustained Achievement Award for outstanding research in 2014.

Erik Seeman.

Erik Seeman is a professor in the Department of History, College of Arts and Sciences. The former director of UB’s Humanities Institute, he is a noted historian of early America and the Atlantic world.

His research focuses on colonial North America, religion, social and cultural history, Indigenous history, and death. He is the author of four books and numerous articles. His most recent book, “Speaking with the Dead in Early America,” won the 2020 Lawrence W. Levine Award from the Organization of American Historians for the best book of American cultural history.

His work has been supported by a National Endowment for the Humanities Fellowship and a 2005 Fulbright Research and Teaching Fellowship. In 2022, he received a Fulbright Scholar Award to teach and conduct research in Germany.

Sarah Xin Zhang.

Sarah Xin Zhang is a professor in the Department of Ophthalmology, Jacobs School of Medicine and Biomedical Sciences. She is an international leader in ophthalmic research, conducting innovative and impactful translational studies on the retina and retinal disease in diabetes.

Her seminal work has potential clinical applications, particularly in targeting endoplasmic reticulum stress to prevent and treat neuronal degeneration in the retina. Recently, her research identified novel neuroprotective factors for retinal neurons.

Her current research studies the detrimental effects of smoking on retinal cells and the cell mediators that attenuate smoke-extract-induced stress and cell damage — research that has opened the door to mechanisms of protecting retinal cell survival and activity.

Zhang received a SUNY Chancellor’s Award for Excellence in Scholarship and Creative Activities in 2023.

The Society's announcement reads, in part:

Forty-six mathematical scientists from around the world have been named Fellows of the American Mathematical Society (AMS) for 2021, the program's ninth year.

The Fellows of the AMS designation recognizes members who have made outstanding contributions to the creation, exposition, advancement, communication, and utilization of mathematics. The AMS is pleased to present the class of 2021 Fellows who are being recognized by their peers for their contributions to the profession, and also to honor excellence.

"It is a great pleasure to offer my sincere congratulations to the new AMS Fellows, honored for their notable contributions to mathematics and to the profession. We are grateful to the nominators and the members of the selection committee for helping the AMS recognize the achievements of their esteemed colleagues through this fellowship." says AMS President Jill C. Pipher.

The American Mathematical Society is dedicated to advancing research and connecting the diverse global mathematical community through our publications, meetings and conferences, MathSciNet, professional services, advocacy, and awareness programs.

Buffalo has a long affiliation with the AMS. In 1896, the Colloquium of the American Mathematical Society was born in Buffalo, and continues today with the lectures through the years. Learn more.
