I am a postdoc in the Simons Collaboration on Global Categorical Symmetries, supervised by Dan Freed at CMSA. Previously I was a graduate student at Notre Dame working with Christopher Schommer-Pries.
My research at the moment is on a specific combinatorial model for the oriented cobordism higher category and infinity-categorical aspects of that construction. My thesis project concerned 3-dimensional TFTs arising from physics and algebraic geometry. I am also interested in (and motivated by) manifold topology, simplicial methods, and categorical logic. On the side, I enjoy reading mystery novels and cooking.
My email is lorenzo (at) cmsa (dot) fas (dot) harvard (dot) edu.
