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, CABA Facility Manager

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.

Gary Wu, Junior Specialist

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.

Saikrithika Gandhi, Junior Specialist

Saikrithika Gandhi (M.S., Environmental Toxicology, RMIT University, Melbourne) conducted her graduate school research on the effect of organophosphates AChE activity in Australian fresh water species Daphnia and Paratya. Currently, she works in the Aquatic Health Programwhere she studies the effects of contaminants, salinity and other environmental stressors onfish in SFE using enzymatic biomarkers such as AChE, Na+/K+ATPase and CYP4501A. Shealso assists the laboratory manager in culture and maintenance of the copepods by monitoring thehealth and welfare of the colony.

Scott Wagner, Junior Specialist

I am a Junior Specialist in the Aquatic Toxicology Lab with a B.S. in Environmental Toxicology from UC Davis.  In the lab, I have experience conducting basic water toxicity tests on ambient waters from the Sacramento-San Joaquin River Delta.  These tests involve successful culturing of the species P. promelas, H. azteca, S. capricornutum, C. dubia, and M. beryllina.  I also have experience working on sediment toxicity tests with H. azteca and in situ river exposures.  Completion of these toxicity tests requires thorough maintenance and evaluation of water quality control parameters.

The effects of salinity on longfin and delta smelt larvae, juveniles, and adult delta smelt. I work in collaboration with the Fish Conservation and Culture Lab (UC Davis) to study these species. Evaluation of culture conditions to identify physiological biomarkers at different life history stages of both species.  I perform feeding, histological, protein assay, and bloodwork analyses to understand salinity tolerances of these species, studies which may benefit the understanding of these species in the wild and further the development of a refugial population for longfin smelt.  Post-doctoral fellow for California Sea Grant/Delta Science Program.
