Ph.D. Biology, University of Arizona. Currently serves as Fishery Biologist (Research) with the Western Fisheries Research Center, Dixon Duty Station. Research interests include aquatic ecotoxicology, water quality tolerances of fish, and life histories and habitat requirements of inland and estuarine fishes.

Dr. Saiki has conducted numerous investigations on environmental contaminants associated with agricultural drainwater, acid-mine drainage, historical gold mining activities, and other land uses in California. His work in the San Joaquin Valley identified selenium as a major contaminant of brackish subsurface agricultural drainwater and helped to document the geographic (spatial) extent and severity of contamination in aquatic food webs and fish. In addition, he has investigated the water quality tolerances and habitat requirements of ESA species such as Lost River and shortnose suckers in Upper Klamath Lake, the Santa Ana sucker in the Los Angeles basin, the desert pupfish in the Salton Sea, and the California freshwater shrimp in streams north of San Francisco Bay. Saiki holds a courtesy appointment as adjunct professor in the Fisheries Department at Humboldt State University.
