His research program focuses on a mechanistic, empirically-based balance of field observations and measurements, experimentation, analysis, and modeling with an emphasis on sampling or experimenting with the appropriate life stages of species from relevant habitats and seasons that are consistent with the goals and objectives of the research question.Recent research topics included:Diagnosing processes that affect marine survival and size-selective mortality of steelhead, Chinook and coho salmonClimate impacts on salmonids in watersheds, especially lake and reservoir food websFeasibility of reintroducing salmon above dams based on food web processes, climate & environmental variabilityImpacts of Artificial Light at Night (ALAN) on salmon behavior and predation mortalityDevelopment and application of bioenergetics models to address problems related to climate impacts, other environmental stressors (hypoxia, salinity, disease, contaminants, pH, etc.), quantitative food web interactions, invasive species, feasibility of species introductions, management of regulated riversDevelopment and application of visual foraging models to address problems related to impacts of artificial light at night (ALAN), the role of the visual environment on the structure and function of aquatic food webs" } ], "hasOccupation": [ { "@type": "OrganizationalRole", "startDate": "2025-03-20T10:52:45.001630", "affiliatedOrganization": { "@type": "Organization", "name": "Western Fisheries Research Center", "url": "https://www.usgs.gov/centers/western-fisheries-research-center" }, "roleName": "Chief-Ecology Section" }, { "@type": "Occupation", "additionalType": "self-claimed professional experience", "name": "Chief, Ecology Section (May 2016-present), U.S. Geological Survey, Western Fisheries Research Center, 6505, NE 65th St., Seattle, WA 98115.
