I did my PhD at UCLA under the supervision of Matthias Aschenbrenner,

and then did a postdoc at the Hebrew University of Jerusalem under the supervision of Ehud Hrushovski.

My CV, a statement about some aspects of my research, and some questions that I believe to be worthy of attention but will probably not work on.

Here is a poster produced by a Fall 2018 undergraduate research group on automata theory and enumeration systems.
