Research Interests

My research training was in the areas of set theory and logic. In particular, I have published papers dealing with infinitary combinatorics and large cardinals. More recently I have become interested in modeling and applications of mathematics to biology. I have also been fortunate enough to work with members of the Institut für Medizinische Biometrie at the University of Tübingen.
