Degrees: 

M.S. Ecology, UC Davis, 2017

B.S. Marine Biology, UC Santa Cruz, 2006

Research Interests:

My research focuses on the movement ecology of California fishes.  Frequently, I use acoustic telemetry to track the movements of fishes in areas where direct observations are nearly impossible to make.  I investigate the drivers of movement and survival of these fish as they traverse the watershed.  I am particularly interested in identifying and examining the consequences of high mortality zones for juvenile Chinook salmon along their emigration corridor from the rivers of the Central Valley to the Pacific Ocean.
