Degrees:BA, Cornell University, 2004.Research:My research primarily focuses on the forces and conditions that generate phenotypic and genetic variation in nature. Mostly, I study the role of landscapes and environments on population structure, gene flow, divergence, and adaptation in amphibians. These interests fall into three general areas: 1) landscape genetics, 2) phylogeography, and 3) the evolution of phenotypic variation.I am particularly interested in identifying methods for integrating environmental and genetic data and in using these approaches in comparative studies of genetic and phenotypic variation. Currently, I am examining patterns of population structure across different networks of populations in the California tiger salamander (Ambystoma californiense), to understand how different landscapes can affect gene flow within a single species, and in the Western toad species complex (Bufo boreas, B. exsul, and B. canorus), to identify whether similar landscapes influence closely related species in the same ways. I am also examining the influences of environmental and geographic variables on genetic and phenotypic variation in the strawberry poison-dart frog species complex (Dendrobates pumilio, D. granuliferus, and D. histrionicus). |
