Rate My Professor Uri Onn

Professor Uri Onn holds the position of Professor in the Mathematical Sciences Institute at the Australian National University. His research specializes in representation theory, with particular emphasis on analytic and algebraic groups. Key areas include representation zeta functions of arithmetic groups, principal series for general linear groups over finite commutative rings, regular characters of groups of type A_n over discrete valuation rings, and base change in representation growth. He previously held a faculty position at Ben-Gurion University of the Negev in Beer-Sheva, Israel, where he taught courses such as Lie Groups. At ANU, he has advanced through the academic ranks and was promoted to Level E Professor.

Onn received an Australian Research Council Future Fellowship in 2016, valued at $814,717, for his project on representations of arithmetic groups and their associated zeta functions. He leads additional research projects, including Geometry of Character Varieties. His publications include 'Arithmetic Groups, Base Change, and Representation Growth' (Geometric and Functional Analysis, 2016, with N. Avni, B. Klopsch, C. Voll), 'Similarity classes of integral p-adic matrices and representation zeta functions of groups of type A2' (Proceedings of the London Mathematical Society, 2016, with N. Avni, B. Klopsch, C. Voll), 'Regular characters of groups of type A_n over discrete valuation rings' (Journal of Algebra, 2018, with R. Krakovski, P. Singla), 'A family of class-2 nilpotent groups, their automorphisms and pro-isomorphic zeta functions' (Mathematische Zeitschrift, 2018, with M. N. Berman, B. Klopsch), and 'Principal series for general linear groups over finite commutative rings' (Communications in Algebra, 2021, with T. Crisp, E. Meir). His research has accumulated 489 citations, with an h-index of 13. Onn teaches courses such as Advanced Algebra 1: Groups, Rings and Linear Algebra (MATH2322), Introduction to Mathematical Thinking: Problem-Solving and Proofs (MATH6222), and Special Topic in Mathematical Sciences (MATH6209). He has delivered public lectures, including 'On rational and irrational numbers, strings and harmony' during National Science Week, and participates in events like the Australian Algebra Conference. He supervises research students and maintains an active collaboration network.
