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.
