Catherine E. Wagner, PI

Katie is an evolutionary biologist with broad interests in processes of speciation and diversification. Her research uses population genetic, genomic, phylogenetic, and comparative methods to study diversification, from speciation processes to macroevolutionary patterns of biodiversity.

Katie received her BA in Biology and Geology from Whitman College, and her PhD from the Department of Ecology and Evolutionary Biology at Cornell University. She did a postdoc with Ole Seehausen at EAWAG/University of Bern in Switzerland before joining the Biodiversity Institute and the Department of Botany at the University of Wyoming as an assistant professor in Fall 2015. She is the recipient of the 2015 Dobzhansky Prize from the Society for the Study of Evolution.


Will Rosenthal, PhD student

Will completed his MS in the Wagner lab at the University of Wyoming in 2021 after finishing a dual BS in Wildlife Studies and Genetics at the University of Wisconsin, Madison in 2018. His undergrad research project focused on genetics of invasive guppies in Hawaii. At the University of Wyoming, Will worked for his MS on the genetics of Yellowstone Cutthroat Trout and its hybridization with introduced rainbow trout. He used genomic data to understand the impacts of genetic ancestry on migration timing, mate choice decisions, and fecundity and survival in the wild. For his PhD, he is expanding in geographic scope and studying range wide patterns in genetic diversity and connectivity for Yellowstone Cutthroat Trout, as part of a large multi-state collaboration. His work is in close collaboration with Annika Walters’ lab.

Join us! We have funded projects for several new graduate students starting in 2023!


Rosebud, lab mascot

Rosebud joined the world and the lab in 2018, and is enthusiastically learning about ecology, evolution, and being a good puppy. You can follow her adventures here.
