The goal of my research is to identify, clone, and characterize the evolution of genes underlying natural adaptations in order to determine the types of genes involved, how many and what types of genetic changes occurred, and the evolutionary history of these changes. Specific areas of research include: 1) Genetic analyses of adaptations and interspecific differences in Drosophila, 2) Molecular evolution and population genetics of new genes and 3) Evolutionary analysis of QTL and genomic data.
