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!
