Short Research Description:
Evolutionary and population genetics of adaptation and disease
Full Research Description:
We study the evolutionary processes that give rise to genetic and phenotypic differences between individuals, populations and closely related species. Specifically, we use mathematical models to better understand these processes, and statistical analyses to identify their footprints in data and make inferences about them. Our current work focuses primarily on the evolutionary causes of adaptation and disease, but we also study a variety of other topics.
