Research Interests

My research has focused on population genetics. I am particularly interested in developing realistic and computationally tractable models for analyzing DNA sequence data. The aim is to understand how fundamental evolutionary processes such as mutation, genetic drift, genetic recombination, and natural selection interact with one another, and the impact of these interactions on evolution.
