Stony Brook University - Department of Mathematics
I am currently an NSF Postdoc at Stony Brook University in the Mathematics Department. From August 2018 to June 2020, I was a postdoc at the University of Utah. In May of 2018, I completed my Ph.D. at the University of Michigan under the supervision of Mircea Mustaţă.In the fall of 2020, I will be on the tenure track job market. Here is my CV.
Algebration geometry: birational geometry, singularities, Fano varieties, K-stability, and moduli.
