I am a postdoc of Mikołaj Frączyk at the Dioscuri Center "Random Walks in Geometry and Topology" at the Jagiellonian University in Krakow, Poland.
I completed my Ph.D. in the math department at UW-Madison under the supervision of Andrew Zimmer and Sebastian Hurtado-Salazar. Prior to studying in Madison, I was an undergrad at the University of Chicago.
Here is a copy of my CV.
Note: I believe artificial intelligence (AI) is very harmful to mathematics and the mathematical community. Consequently, I do not, nor do I plan to, use AI in any form in my mathematical works. This beautiful blog post of Hugo Duminil-Copin describes many of the concerns I have with the use of artificial intelligence in mathematics.

Mathematical Interests:
My mathematical interests are in geometry and dynamics, particularly discrete subgroups of higher rank Lie groups. Recently, I have been especially interested in understanding asymptotic properties of discrete subgroups of Lie groups and the representation theory of semisimple Lie groups.
Other:
My thesis (essentially a combination of papers (1) and (2) above).
