Summary of Expertise

My research has focussed on anthropogenic stressors to anadromous fishes. Species such as Chinook salmon and green sturgeon face tremendous challenges in California, where the landscape they evoloved to thrive in has been altered by human development since the gold rush. I specialize in applying technologies that allow us to study organisms that migrate over long distances or are difficult to observe in nature. These include telemetered tracking, acoustic camera and sonar systems, remote sensing and hydrographical data collection. My work has been both field based -- chasing the full life cycle of salmon migrating from Sierra Nevada headwater streams out to the Pacific Ocean. As well as laboratory based -- studying the physiological effects of water quality on fish using respirometry and swim flumes.
