Matthew R. Ballard

Professor in the Department of Mathematics at UofSC and a member of the SC AG NT group.

I study algebraic geometry 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.

For more information about me, see my CV. For a list of my papers, please view the publications page.

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.
