I am interested in understanding how stream flows influence the evolution and ecology of freshwater fish. My research project is focused on the evolutionary ecology of life history strategies in Oncorhynchus mykiss, also known as steelhead/rainbow trout. O. mykiss life history strategies can be categorized into two divergent forms, the ocean-migrating form, or steelhead trout, and the stream-resident form, or rainbow trout. I am interested in how natural waterfalls influence the distribution of genetic diversity that is linked to life history strategy. I am also interested in understanding how life history genetic diversity results in a variety of ecological effects in the stream, including differences in the density and behavior of O. mykiss.
