Position description
Research in the Segarra Lab focuses on understanding how fish respond to environmental change and anthropogenic stressors. Our research examines the effects of environmental contaminants and stressors such as temperature and salinity using physiological and behavioral endpoints, complemented by molecular approaches, with applications to fish health and conservation.
The position includes fish husbandry, experimental exposures, behavioral and physiological assays, fish handling and dissection, biological sample processing, and data collection.
Laboratory studies will include controlled exposures to environmental contaminants, including insecticides and other chemicals, and experiments evaluating fish responses to temperature and salinity. The incumbent will conduct behavioral and environmental-tolerance assays. The position will also involve building and maintaining aquaria and experimental systems, including associated plumbing.
Field activities will include fish transport and collection of biological and environmental samples. Some field work will be conducted from boats and under variable weather conditions. Field work may involve carrying loaded coolers and other research materials weighing as much as 50 pounds.
Work will occur in both temperature-controlled facilities and wet-laboratory spaces where temperatures may vary considerably. Because fish care and experimental schedules do not always fall within regular working hours, the incumbent will be required to work evenings and weekends when necessary.
Travel between research facilities and/or field locations is part of the position. A valid driver’s license and acceptable driving record are required.
The successful candidate should be organized, dependable, attentive to detail, and have strong problem-solving and communication skills. The position requires the ability to work both independently and collaboratively.
The Junior Specialist will have opportunities to contribute to research reports and scientific publications and to present research findings at scientific or technical meetings.
The duties of this position are designated as follows:

Position description: Research conducted in the Segarra Lab focuses on environmental tolerance to anthropogenic change. This involves utilizing numerous fish species upon which the effect of thermal and salinity stress, contaminant exposure and disease are evaluated using molecular and physiological performance endpoints. The research also incorporates environmental DNA analyses for pathogens associated with fish. The candidate would be willing to assist in all aspects of research, predominantly assisting with molecular approaches; RNA/DNA extraction, cDNA synthesis, quantitative PCR, as well as helping with field and lab-based fish exposures, fish care and maintenance, dissections, sample processing, and data analyses, as required. The candidate will discuss results upon completion and plan appropriate follow up experiments with PI and Post-doctoral researchers. Candidates will assist our research team in 1) understanding the sublethal effects of stressors on fish, with direct implications for the conservation of these species, and 2) monitoring fish pathogens in the San-Francisco Bay-Delta. The applicant will preferably have experience working with fish species.
General responsibilities include the care of sensitive fish species and Zebrafish, coordinating and assisting with exposures using chemicals (e.g., insecticides) and behavioral assays in a wet laboratory. Candidates will also be expected to assist with fish euthanization and dissection. They will occasionally be working in Quonset Hut-type laboratories where temperatures can vary and in temperature-controlled offices and laboratories. Because research involves animals, candidates should be available to work weekends and evenings as required.
