My research is in the field of set theory. Most of my recent work is on ideals associated to large cardinals. For example, I've done work on combinatorial principles and forcing constructions related to the large cardinal properties of indescribability and Ramseyness. I've also worked on strong properties of successor cardinals that hold after collapsing large cardinals and on preserving large cardinals through Easton-support forcing iterations.

We hosted a MAMLS meeting at VCU on April 1 & 2, 2017. Thanks to Arthur Apter and Hugh Woodin for their generous support.

See the VCU Analysis, Logic and Physics Seminar (ALPS) website for upcoming talks.

I got my Ph.D. with Joel D. Hamkins at the CUNY Graduate Center.

Here are some notes from a course in model theory, which I taught jointly with Sean Cox, and which was offered in the spring of 2014 at VCU.
