I am a Visiting Assistant Professor in the Math Department at Cornell.

Logic and set theory are my primary research interests. My research focuses on definable sets of reals, especially in forcing extensions and under large-cardinal hypotheses. I am also interested in what can be said about mad families and other combinatorial objects from a descriptive-set-theoretic perspective.

In June 2018 I finished my PhD at UCLA under the supervision of Itay Neeman.
