Genome Evolution, Transposable Elements, RNA silencing, Epigenetics, and Molecular Evolution

My research is focused on understanding how genetic conflict shapes the evolution of systems of inheritance. Meiosis and sexual reproduction are prevalent across the tree of life, but they can be exploited by genetic parasites in ways that harm the host. I am particularly interested in understanding how this genetic conflict shapes the evolution of genetic and epigenetic systems. We are especially interested in answers to the following questions: How do RNA silencing mechanisms evolve in the face of varying transposable element content across species? How does the persistence of genetic conflict shape mechanisms of epigenetic gene control by small RNAs?  What are the mechanisms underlying changes in the rate of recombination? Are these changes driven by natural selection or drift? How has conflict shaped the machinery of meiosis? To answer these questions, we work with different species within the Drosophila genus, including Drosophila melanogaster and Drosophila virilis. The lab uses a wide variety of approaches including cytogenetics, bioinformatics, molecular genetics and population genetics. We are especially interested in the evolutionary dynamics of transposable element control and gene regulation by piwi-interacting RNAs (piRNAs). Overall, we hope to integrate the experimental approach within a broader theoretical framework.
