I am a Postdoctoral Research Associate in the Department of Mathematics at Princeton University.
My area of research is algebraic geometry and my postdoc mentor is János Kollár. Previously, I was an
Instructor at Princeton. I received my PhD from the University of Massachusetts, Amherst, under
the supervision of Paul Hacking. In my thesis, I studied the
Morrison cone conjecture for log Calabi-Yau surfaces.
