I am a postdoctoral member of the Institute for Advanced Study. Previously, I was a postdoctoral fellow at the Max Planck Institute for Mathematics and a graduate student at the University of Michigan, advised by Bhargav Bhatt. My research interests lie in arithmetic and algebraic geometry.

I am currently not teaching.

At Michigan, I was an instructor for Math 115 and Math 116, a lab instructor for Math 215, and a math instructor for the M-STEM Academies summer program.
