Research
My group is focused on the process of Adaptive Evolution, during which species adopt novel traits to overcome challenges. We study the evolutionary patterns of genomic elements to determine the genetic changes underlying adaptive evolution and to discover previously unknown genetic networks. These discoveries have already led to advances in human health, species conservation, and basic molecular biology. To meet these goals we have developed a suite of computational and experimental approaches employing comparative genomics, proteomics, and zebrafish genetics. Ultimately, our research program develops an evolutionary model in which genomic elements are shaped by their co-evolution with other elements, their environment, and interactions between the sexes.
