As a research fish biologist, I work towards addressing the grand challenges in organismal biology, such as: 1) understanding the molecular and cellular mechanisms underlying species-specific responses to environmental manipulations, 2) gain physiological insight to predict ecological and environmental change, and 3) understanding the role of an organism in the environment. I combine highly controlled laboratory experiments with field-based studies to gather information for resource managers. I incorporate modern molecular techniques (e.g. 454 sequencing and qPCR) with traditional measurements (e.g. growth, bioenergetics, mortality, fecundity, etc.) to better understand the relationships between the environment and the animal. Therefore, I am a member of several interdisciplinary research teams focused on developing controls for invasive species and effects of contaminants in the Great Lakes Region. I possess a Bachelor’s and Master’s degree from Michigan State University in Fisheries as well as a doctorate in Animal Physiology from the University of Idaho. I spend much of my free time fly-fishing, hiking/backpacking, skiing and snow-shoeing with my wife, Shannon.
