The objective of my research is to combine fieldwork, laboratory research, and mathematical modeling to better inform policy decisions about the delta smelt (Hypomesus transpacificus) a fish endemic to San Francisco Estuary-Delta.


Listed as threatened, this tiny fish exerts a major influence upon state water management. Because its habitat overlaps with Delta pumping facilities that transfer California water, the listed status of the fish can shut down water operations and create conflict between managing water for environmental protection and for water users. Such a “smeltdown” impacts California’s economies, ecosystems, and 23 million users that depend on the Delta for fresh water. My research emphasizes the need for collaborative efforts to better understand mechanisms driving delta smelt population levels . I hope to facilitate additional communication and collaboration between the U.S. Fish and Wildlife Service, California Department of Fish and Game, California Bay-Delta Authority, University of California campuses, water operators, and concerned California citizens.
