Limited Term Assistant Professor My name is Yukun Du, currently a Limited Term Assistant Professor at the Department of Mathematics at UGA. I earned my Bachelor's Degree at Tsinghua University and my Ph.D. at UC Davis. My research interest focuses on Geometric Group Theory and Symmetric Spaces. Research Research Areas: Geometry Topology Research Interests: My research interest focuses on Geometric Group Theory, especially Kleinian groups (for both hyperbolic and higher-rank symmetric spaces). My Doctoral Thesis, Geometry of Selberg's bisectors in the symmetric space $SL(n,\mathbb{R})/SO(n,\mathbb{R})$, discussed topics related to an algorithm for discrete subgroups of $SL(n,\mathbb{R})$ acting on this symmetric space. I am also interested in Bruhat-Tits trees and buildings. Selected Publications Selected Publications: “Geometry of Selberg’s bisectors in the symmetric space SL(n, R)/SO(n, R)”. In: J. Lond. Math.
