Hello! I am an NSF Postdoctoral Fellow at the University of Michigan, mentored by Professor Mircea Mustaţă.
I am interested in algebraic geometry and its connections to arithmetic geometry and commutative algebra;
in particular, I am interested in rationality of algebraic varieties and in positive characteristic algebraic geometry.


I received my PhD from Princeton University in 2021 under the supervision of Professor János Kollár.
Before that, I was an undergraduate at Columbia University, where I graduated in 2016.
