Research Interests


I have broad interests in the evolution and conservation of anadromous fishes. My research combines surveys of genetic and phenotypic variation with population demography and intraspecific life history variation to examine the evolutionary ecology of wild populations over contemporary time scales and in response to anthropogenic disturbance. My work provides important linkages between evolutionary ecology and applied conservation, and conveys valuable insights about the ability of populations to adapt to dynamic environmental change.
