Evolution, speciation, population genetics and genomics
Current research in the Harrison laboratory focuses on using genetic, genomic, proteomic, and phylogenetic approaches to gain insights into population structure, evolutionary relationships and the origin of species. We are interested both in how DNA and protein sequences change over time and in using these changes as markers for understanding pattern and process in evolution. Much of the research in the Harrison lab is directed toward understanding the origin of species, the evolution of barriers to gene exchange, and the history and current dynamics of natural hybrid zones. The lab currently focuses on two model systems: (1) a well-characterized mosaic hybrid zone between two species of field crickets and (2) two "strains" of European Corn Borer which differ in pheromone communication system.
