I am a Research Assistant Professor at University of Utah. Starting in Fall 2018, I will be an Assistant Professor at
Purdue University. I obtained my Ph.D in May 2014 at the University of Michigan under the direction of
Melvin Hochster. My research interests are in commutative algebra and algebraic geometry.
My CV is here.
