** I will be on the job market in Fall 2025 **
I am a math graduate student at Cornell University. I did my undergrad at the University of Michigan.
My main mathematical interests are geometric group theory and hyperbolic geometry. In particular I like to think about higher dimensional hyperbolic manifolds and modifying them in order to obtain group theoretic results.
Jason Manning is my advisor.
