My research interests focus on incorporating phylogenomic and population genomic techniques to understand how environmental variation and natural histories mediate population structure, local adaptation, and genetic differentiation through time. My dissertation research will address these themes in terrestrial (garter snakes) and marine (sea slugs) systems. Co-advised by Dr. Chris Feldman, I will utilize a Genotyping-by-Sequencing (GBS) approach to investigate the evolution history of tetrodotoxin resistance, introgression, and phenotypic variation between populations of garter snakes (Thamnophis). In addition, I will also investigate how development, dispersal ability, and geographic barriers shape genetic differentiation and responses to changing environments in along the California coast using sea slugs (Aplyisa californica, Okenia rosacea, and Phidiana hiltoni) as a case study.
