Chelsea Rochman, Postdoctoral Researcher

I am a Postdoctoral Fellow in the Aquatic Health Program at UC Davis with areas of emphasis in Marine Ecology and Environmental Toxicology/Chemistry. Particularly, I am interested in sorption of persistent organic contaminants (PAHs,PCBs, OCs, and PBDEs) to plastic debris in the marine environment and from plastic debris (nonylphenol, styrenes and flame retardant) into the marine environment. My main interests involve how toxicants associated with marine plastics transfer to organisms upon ingestion and consequently affect their health. Outside of my dissertation research I have attended several policy meetings regarding this environmental issue and am participating in an NCEAS working group focused on marine debris. I also participate in outreach activities such as the Girls in Ocean Science Conference in Dana Pt, CA to translate my research beyond academia. My ultimate career goal is to stay in academia and continue to research environmental toxicology/chemistry while educating the community through public outreach to inform science, policy and the general public.

Linda Deanovic (B.S., Zoology, University of California, Davis, 1986) has been managing the University of California, Davis, Aquatic Toxicology Laboratory for over 25 years. During this time, she has managed research projects related to ambient monitoring programs that utilize standardized toxicity test methods as well as developmental protocols for indigenous species. She has over 20 years of experience conducting Toxicity Identification Evaluations and dose response tests for an assortment of species and chemicals. In addition, she served as a quality assurance advisor for a California wide program for one year.

My research focuses on Bisphenol A (BPA), one of several endocrine disrupting chemicals (EDCs) commonly found in aquatic systems. BPA has been shown to induce estrogenic effects in fish affecting body growth, sexual maturation, developmental reproductive function, and brain structure in vertebrates even at low levels of exposure. I utilize protein synthesis, coupled with traditional measures of toxicity (e.g. histopathological analysis), to correlate genetic responses to the toxicological effects of BPA.

Assigned on the Flash Study, he assists in research by collecting general health of Delta Smelt from dissected samples for data analysis. Processing of tissue is also done through a system of formalin, parafinn, embedding, sectioning, and staining into histopathology slides. Other duties include assisting Ching on maintenance of medakas, copepods, and overall lab inventory and general lab safety.

My research focuses on physiological responses of fish to environmental factors, though I also have a vested interest in fish behavior and ecology.  Currently, I look at the effects of salinity on Longfin and Delta smelt. I’ve been most interested in understanding their responses to low salinities, for application to monitoring in the San Francisco Bay Estuary. If these species can survive salinities above 6 parts per thousand that often define that of the Low Salinity Zone, then other factors must be contributing to their apparent habitat preference for this area.  I primarily work with adult Delta Smelt, though have collaborated with the Fish Conservation and Culture Lab  to study other listed species and identify conditions useful for their culture. 

Previously, I studied physiological limits of temperature in unimpounded streams housing rainbow trout and steelhead. I also obtained my degree from the University of California, Davis, looking at salinity acclimation of tilapia, a model species for estuarine fish.

I am a Post-doctoral Fellow for California Sea Grant/Delta Science Program.

Bruce G Hammock, Postdoctoral Researcher

My research combines observational and experimental data to broaden our understanding of aquatic ecology. I am particularly interested in addressing tractable environmental problems. My previous research focused on the behavioral ecology of stream herbivores (i.e., the timing and causes of mayfly drift) and how it is affected by global change (i.e., climate change, invasive species and the interaction between the two). More recently, I examined how stream community recovery on disturbed substrate is affected by silk deposition of black fly larvae. My current projects include quantifying how osmoregulatory energy costs influence feeding rates in an esturarine copepod and analysis of spatially and temporally explicit delta smelt biomarker data.
