My research interests in theoretical population genetics are very broad. They include:

• Evolution in rapidly adapting populations: coalescence, patterns of genetic diversity, and the role of genetic draft.
• Game theory and the evolution of cooperation, especially in populations experiencing strong selection.
• Stochastic processes and the establishment or invasion of beneficial mutations.
• Information theory and statistical physical analogues of evolution.

For my bachelor's thesis, I performed bioinformatic and genomic analyses to detect signs of "preadaptation" in Saccharomyces cerevisiae 3' UTRs. In my doctoral dissertation, I developed a novel and parsimonious method for inferring the "escape rates" (selection coefficients) of beneficial mutations in HIV during acute infection. I also worked on the population genetic theory of rapid adaptation and devised methods for distinguishing between the effects of genetic drift and genetic draft.
