I am a Hendrick Assistant Adjunct Professor at UCLA. My postdoctoral mentor is Mike Hill and I am part of the topology group.

My interests are in homotopy theory and algebraic geometry. In my thesis, I focused on the construction and classification of complex topological vector bundles of rank three on complex projective five-space. I am currently preparing this work for publication, and thinking about generalizations of its contents. Please email me if you would like a copy of my thesis or a research statement.

My other projects have involved: studying analogues classical invariants (degree, Euler characteristic) in motivic homotopy theory and developing a theory of localization in homotopy type theory (analogous to that for spaces). Additionally, I spent some time during grad school thinking about characterizations of weak equivalences in the Joyal model structure on simplicial sets (no resulting publication). As an undergraduate, I studied extremal effective divisors on the moduli space of stable rational curves with marked points.

Before UCLA, I completed my PhD at Harvard, where I worked with Mike Hopkins. I did my undergraduate at the University of Massachusetts Amherst, where I wrote an honors thesis in algebraic geometry with Jenia Tevelev. Prior to that, I earned an Associate's degree at Cape Cod Community College.

I am an organizer for the MIT Talbot Workshop, along with Calista Bernard, Yajit Jain, and Lucy Yang. If you have questions or suggestions related to Talbot, contact me or e-mail talbotworkshop AT gmail DOT com.

My CV is available upon request.
