I was born in Richmond, VA, obtained an undergraduate degrees in Mathematics at VCU, finished my PhD at the City University of New York with Joel David Hamkins in 2012, and now I am an associate professor at VCU.

Previously I held visiting positions at the Fields Institute, University of Prince Edward Island and VCU.

My research is in the area 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 Ramseyness, ineffability and indescribability. 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.
