I am a mathematician, working in geometric representation theory, with an emphasis on the modular representation theory of reductive algebraic groups, and in related areas of geometry and combinatorics. I have been an Assistant Professor of Mathematics at Westlake University, a Research Fellow in the School of Mathematics and Statistics at the University of Sydney, and a Postdoctoral Researcher at Louisiana State University. I recieved my Ph.D. from the University of Georgia in 2016 under the supervision of Daniel Nakano.
