Matthew R. Ballard
Professor in the Department of Mathematics at USC and a member of the SC AG NT group.
I study categorical structures and am particularly interested in questions arising from mirror symmetry. Much of my current work focuses on derived categories and their relation to more classical questions in geometry and arithmetic. I am also interested in formal verification, particularly of modern mathematics.
For more information about me, see my CV. For a list of my papers, please view the publications page.
I recently joined the maintainer group for Mathlib, the expansive library of mathematics formalized in the Lean programming language. I always welcome a chat about how formalization, particularly Lean, can make your life better in the age of AI.
For a little of my pedagogical philosophy and experience, see my teaching page. As an extension of teaching, I take pride in mentoring researchers at all stages and I regularly organize mathematical events, even virtual ones. If you are interested in participating in such an event, please contact me.
