Department of Fisheries and Wildlife

I integrate animal behavior, physiology, and landscape ecology to better understand how fish and wildlife interact with their environment. My research employs observational study, field experiments, and simulation modeling.

Our research focuses on the pathogens that affect the health of wild Pacific salmon populations, particularly myxozoan parasites, which have a complex life cycle, requiring both a fish and annelid host.

Salmon diseases, host resistance mechanisms, parasite evolution.

My research has focused on (1) the effects of agricultural and forestry land-use practices on stream and riparian habitats critical to native fish species, and (2) the development of land management practices that minimize degradation of stream and riparian functions important to aquatic species.

Current research interests include

•land-ocean interactions and human influences on coastal water quality and biodiversity (including climate impacts, and land-based pollution)

Fish Ecology, Fish-habitat relationships, Restoration, Aquatic-terrestrial linkages, Ecological literacy in contemporary culture

Reproduction; Physiology

Clean Water Act Policy (esp. water quality standards)

I am interested in the ecology of early life stages of marine species and the constraints imposed by the environment. I am particularly interested in the pervasive influence on temperature variation on all aspects of physiology and ecology of ectotherms.

Research Areas: Aquaculture; nutrition of oysters and other bivalves; microencapsulation; polyculture of abalone; genetic selection of oysters.

Research Areas: Marine ecology, fisheries science, otolith chemistry, mixing and migration, early life history

Research Areas: Fisheries genetics and genomics, fisheries conservation and management.

Research Areas: Fishery stock assessment and management; development and testing of stock assessment methods; models of fishermen's behavior (e.g., fishing operations such as gear and fishing location choice).

I am researching the effect that climate change has on Pacific salmon.  Specifically, I statistically analyze how major climatic events (El Nino and La Nina) affect the respectively nutrient-rich and nutrient- poor oceanographic episodes (upwelling and downwelling).

Marine fish stock assessment and fishery harvest theory, statistical methodology, risk analysis and precautionary approaches, prevention of overfishing.
