Degrees:

2005: University of California, Davis. Wildlife and Fish Conservation Biology – B.S. Conservation Biology

Research Interests:

Native California anadromous and freshwater fishes; temperature preference, swimming performance, behavior, stress responses and recovery of sturgeon near fish passage/way structures; environmental requirements of native fishes for conservation efforts; physiological ecology (including bioenergetics and osmoregulation); effects of pulsed-flows in altered river systems (fish distribution, physiology, behavior, and movements); salmonids use of submerged vegetation as hydraulic shields in floodplains; studies of fish screens, trash-rack, and deterrents devices.
