I am a Simons postdoctoral member of the Simons Collaboration on Perfection in Algebra, Geometry and Topology group, currently working at Université Paris-Saclay under the mentorship of Kęstutis Česnavičius.
Before that I was a student of Matt Emerton at the University of Chicago, and I graduated in the summer of 2024.

My research interests lie in the area of arithmetic - algebraic geometry. I study singularities and degenerations of varieties in positive and mixed characteristic, along with their connections to number theory and birational geometry.
