Research Interests:

I am interested in the population genetics and fitness consequences of characters that are inherited in a non-Mendelian fashion. I am also interested in the evolution of life history traits and the maintenance of variation in life history traits.

Current Research:

My present research focuses on an endosymbiont bacteria that lives in the reproductive tract of a number of species of flies in the melanogaster species subgroup of Drosophila. The bacteria (Wolbachia) is maternally inherited, and causes mating barriers between lines of flies that carry different strains of bacteria. Males that carry one strain cannot inseminate females that carry another strain of bacteria. I am looking at the DNA variation within and between bacterial strains, and comparing them to the mitochondrial haplotypes of the flies. I am also looking at pre- and post- zygotic mating barriers between flies of various cytotypes within Drosophila simulans.
