Research Projects

I am developing a method that uses DNA to detect endangered fish in the San Francisco Bay and Delta. Delta Smelt are ESA-protected fish endemic to the SF Bay-Delta. They are hard to locate using traditional monitoring methods such as trawl sampling. However, fish can be detected in the wild using the DNA they leave behind in water. This method is called environmental DNA (eDNA) monitoring.

eDNA monitoring may enable more targeted, less invasive, and less expensive monitoring of fish compared with traditional trawl sampling. Better detection of Delta Smelt could help inform conservation and water management strategies in California.

I use genetic methods such as quantitative PCR (qPCR) and high-throughput sequencing (HTS) that have broad application in conservation and management of aquatic species and ecosystems. My MS research (Kimmerer Lab, San Francisco State/Romberg Tiburon Center) used HTS to study plankton food web interactions in the San Francisco Estuary.
