I am a tenure-track assistant professor at the University of Copenhagen. My research is in arithmetic and algebraic geometry.

Previously, I was a postdoc at the Institut des Hautes Études Scientifiques, the Institute for Advanced Study, and the Max-Planck-Institut für Mathematik. I obtained my PhD from the University of Michigan, advised by Bhargav Bhatt.
