Prospective graduate students may contact this person about availability as a faculty advisor.
I conduct and coordinate research on fisheries resources with staff in the Washington Cooperative Fish & Wildlife Research Unit, other faculty at the University of Washington, cooperating state and federal agencies (Washington Departments of Ecology, Fish and Wildlife, and Natural Resources, U.S. Fish & Wildlife Service), and other organizations.
My research program focuses on predator-prey interactions, bioenergetics modeling, behavioral ecology, distribution, growth, population dynamics, and food web dynamics, primarily in large lakes, estuarine, and marine systems. Our investigations quantitatively examine factors limiting populations of interest, including resident and anadromous salmon and trout like bull trout, salmon, kokanee, sport fishes, native fish communities, species introductions, hatchery stocking practices, and re-establishment of resident or anadromous fishes. Our approach combines fisheries-limnological and oceanographic sampling, lab/field experiments, and modeling within a spatial, temporal, and life-stage-specific framework to address basic questions in aquatic ecology and critical issues relating to management and conservation of sensitive species, harvestable species, hatchery-wild species interactions, and ecosystem function in response to natural or human-induced environmental change.
Some current investigations include an examination of climate change effects on distribution, energetics, growth and survival of pink salmon the Gulf of Alaska; investigating the early marine life history, temporal distribution, trophic interactions, growth and survival of salmon in Puget Sound; food web dynamics, growth, survival, distribution, and contaminant bio-accumulation of resident and anadromous fish in large lakes; development and application of visual foraging models for piscivorous and planktivorous fishes.
