What I do

I research the foundations of mathematics and the consequences for infinite structures. My research investigates synergistic interactions between set theory, combinatorics, topology and analysis. Current research focuses include Ramsey theory of infinite structures, the structures of compact spaces, and applications of set-theoretic methods in their analysis.

I teach a wide range of courses from graduate level logic to core math courses for non-majors. I also advise graduate students and mentor postdoctoral scholars.

Professional Biography

Born and raised in the heart of San Francisco, I obtained a BA from Berkeley, with an honors thesis advised by Field's medalist Richard E. Borcherds. I earned a PhD from the University of Minnesota under the supervision of Karel Prikry. My first postdoc was an NSF VIGRE position at Penn State, working with Stephen G. Simpson on recursion theory. After that, I held a three year research position at the Kurt Goedel Research Center for Mathematical Logic in Vienna, headed by Sy-David Friedman. In 2007 I was hired as an Assistant Professor at DU. I became Associate in 2011 and Full Professor in 2016.

Research

I work on the interface of logic, combinatorics, topology and analysis. My research is focused on answering longstanding open problems, developing better methods to approach infinite structures, and making new connections between areas of math which, when seen, help each field progress.
