My research interests include juvenile salmon passage and survival at hydroelectric dams using acoustic and radio telemetry, operate radio telemetry equipment to monitor movements of adult salmon, develop and refine standard operating procedures for surgical implantation of transmitters, and train others in surgical implantation of transmitters. 

I am currently working in the Klamath River Basin studying survival of juvenile Chinook salmon migrating through reaches known to have Ceratomyxa Shasta.  I am also working on a study evaluating the performance of a Bio-Acoustic Fish Fence in the Sacramento River Basin.

I have historically studied urbanization effects on forage fish in Puget Sound (Coastal Habitats in Puget Sound).
