About Me
I am a Ph.D. student at the University of Bonn under the supervision of Jens Eberhardt and Catharina Stroppel. I study applications of motivic homotopy theory to Lie theory and geometric representation theory. More precisely, my current research is focused on understanding categories of K-motives on nice algebraic varieties of Lie-theoretic origin, such as flag varieties and affine Grassmannians.
Before that, I completed my Masters at McGill University in Montréal under the supervision of Joel Kamnitzer.
