  • B.S. in Fisheries, 1998, Utah State University
  • M.S. in Fisheries, 2002, University of Minnesota

Research Interests

I do research in basic and applied freshwater ecology. My current research focus is Pacific salmon conservation, with specific interests in mechanisms of population regulation, predator/prey interactions, and using mercury and other elemental tracers to study fish bioenergetics. Most of my research has a strong field work component because that's the fun part of fisheries biology!
