Person

Dr. James A. Hobbs is a distinguished environmental scientist with over 20 years of experience specializing in the ecology and conservation of fish populations. His research career has been defined by pioneering work in otolith geochemistry, where he has developed cutting-edge techniques such as laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) to analyze trace elements and isotopes in fish otoliths. This innovative approach has enabled Dr. Hobbs to reconstruct the migratory histories, age structures, and habitat use patterns for Delta Smelt, Longfin Smelt, Sacramento Splittail, Green Sturgeon, White Sturgeon, Steelhead Trout, Chinook Salmon in the Central Valley and San Francisco Estuary, providing invaluable data for fisheries management, habitat restoration, and conservation strategies.

Dr. Hobbs’s research has also focused on long-term monitoring of tidal wetland restorations in South San Francisco Bay. In the Alviso Marsh, his research has been documenting the recovery of former industrial salt ponds to tidal brackish marsh supporting a number of estuarine species including the endangered Longfin Smelt. As an Environmental Program Manager at the California Department of Fish and Wildlife, he oversaw one of the longest-running environmental monitoring programs in California, guiding a team of scientists in the design and execution of comprehensive field surveys that assess spatiotemporal variations in fish distributions throughout San Francisco Bay.

In addition to his technical expertise, Dr. Hobbs is a prolific author with numerous publications in high-impact journals, including Ecology, Fisheries, Marine Ecology Progress Series and Canadian Journal of Fisheries and Aquatic Sciences. His work is characterized by a strong emphasis on interdisciplinary collaboration, integrating genetics, toxicology, and population modeling to address complex ecological questions.

Beyond his research and mentorship, Dr. Hobbs is an advocate for diversity, equity, and inclusion within the scientific community. He actively participates in initiatives aimed at increasing representation and inclusivity in environmental science, and he engages with diverse communities to ensure that his research benefits a broad spectrum of stakeholders.

Dr. Hobbs’s career reflects a deep commitment to advancing both the science and practice of fish conservation, with a particular focus on the challenges and opportunities presented by the dynamic and changing ecosystems of the San Francisco Estuary.
