Teaching & Research population genetics, evolutionary , ecology and molecular ecology, conservation biology, evolutionary dynamics, local adaptation, fish, fisheries. joined the Department of Biology in July 2002 after nearly four years at the Danish Institute for Fisheries Research in Denmark.
My research focuses upon questions at the interface of conservation genetics and evolutionary biogeography. Along with my students and collaborators I am interested in addressing issues related to the conservation genetics of marine and anadromous fish under exploitation (either current or historical), and in the evolutionary biogeography (ecology, evolution, phylogeography) of freshwater fish. My current interests in conservation genetics focus upon the broad issue of determining what processes (genetic drift vs. natural selection and local adaptation) are responsible for observed patterns of temporal and spatial population structuring in marine and anadromous species, and on how changes in population size (e.g., from exploitation: harvesting, stocking) affect such patterns. We examine how landscape (or seascape) and life history interact to effect population structure and connectivity (gene flow) in aquatic organisms. |
