I am a Benjamin Peirce Fellow and NSF Mathematical Sciences Postdoctoral Research Fellow, mentored by Hugh Woodin, at Harvard University.

I got my PhD under Rami Grossberg in 2014 at Carnegie Mellon University and spent a year working with John Baldwin at University of Illinois-Chicago before coming to Harvard.

I am organizing the logic seminar at Harvard. It meets Tuesdays at 5:15pm in Science Center 507.

I am currently teaching Math 255 Classification Theory for Tame Abstract Elementary Classes.

I'm interested in tame Abstract Elementary Classes. You can check out Wikipedia for more details, but the essence is that these are classes of structures in which types (appropriately defined as Galois types) satisfy a nice locality condition for equality. This locality condition can be seen as a weak form of compactness that is strong enough to recreated some classification theory, but weak enough to hold in many nonelementary classes.

My primary work and interest is around developing a classification theory for tame AECs. The "test question" here is Shelah's Categoricity Conjecture, but this is more of an organizing/motivating idea than the real goal. The goal is to develop notions of forking and independence that give us similar insight and dividing lines from first-order classification theory.

Beyond this, I'm also interested in model theory and classification theory in other nonelementary settings and concrete examples and applications of this classification theory to other areas of mathematics. Abutting these interests are first-order classification theory (and model theory) and the interaction between model theory and other areas of logic, especially set theory and category theory.

In 2014-2015, I gave several survey talks on tame AECs. An idealized version of the slides are available.

My CV is available (last updated 10/17). My research and teaching statements are also available on request.

I defended my dissertation in May 2014.
