About Me
I am an Assistant Professor in the Department of Mathematics at the University of Utah University of Utah. From 2018 to 20201, I was an NSF postdoc at Stony Brook University and the University of Utah. In 2018, I completed my Ph.D. at the University of Michigan under the supervision of Mircea Mustaţă.
Here is my CV.Research interests
Algebration geometry: birational geometry, singularities, Fano varieties, K-stability, and moduli.
