I am currently a postdoc at the Basque Center For Applied Mathematics, in the Singularity Theory and Algebraic Geometry group. I study algebraic geometry and commutative algebra. Recently, I've been thinking about positivity properties of tangent bundles of Fano manifolds in relation to differential properties of their section rings, and connections to positive characteristic phenomena such as finite F-representation type. I'm also interested in applications of arc spaces to the study of singularities.

Previous to this, I was a postdoc at the University of Utah, and before that I was a graduate student at the University of Michigan. My adviser was Mircea Mustaţă
