My research combines both computational and experimental approaches to address a broad range of topics in Evolutionary Genetics/Genomics including: (1) Quantifying the mode and strength of selection acting on coding and non-coding DNA in the Drosophila genome; (2) Quantifying the impact of changes in population size and and structure on patterns of genome variability in D. melanogaster and its close relatives; (3) Understanding the nature of species boundaries in several Drosophila and Lepidopteran species; and (4) Quantifying recombination rate variation in the genome and its effects on patterns of genome variability and evolution.
