Final date: March 1, 2027
The anticipated start date is January 2027, with flexibility depending on candidate availability.
Location: School of Veterinary Medicine, University of California, Davis.
Position Description
The Segarra Lab at the University of California, Davis (UC Davis) seeks a highly motivated Postdoctoral Researcher with expertise in fish physiology and behavior to join our team. The successful candidate will join a collaborative and interdisciplinary research environment involving faculty, staff and students studying the physiological ecology of California fishes and their responses to environmental change, with the ultimate goal of improving conservation and management strategies. The initial appointment will be for one year, with the possibility of extension for a second or third year, subject to funding availability.
The primary responsibility of the Postdoctoral Researcher will be to oversee and conduct experiments investigating the effects of environmental conditions and contaminant exposure on the physiology and behavior of juvenile Chinook salmon. These projects aim to provide critical information on how environmental stressors influence fish performance during outmigration and the potential implications for salmon conservation and management.
The researcher will participate in field-based exposure studies, including fish cage deployments in collaboration with the Fangue Lab at UC Davis, followed by laboratory assessments of fish physiology and behavior. Experiments may include swimming performance (Ucrit), thermal tolerance (CTmax), physiological stress indicators (e.g., cortisol and blood glucose), and behavioral assays. These assessments will be complemented by contaminant analyses of fish tissues and water samples conducted in collaboration with Southern Illinois University (SIU).
The successful candidate will play an active role throughout the research process, from experimental design and data collection to statistical analysis, interpretation, and scientific communication. The candidate will also be responsible for supervising undergraduate students and coordinating their involvement in research activities. The position offers opportunities to serve as lead author on peer-reviewed publications, present research findings at scientific conferences, and interact with academic collaborators and stakeholders involved in fisheries conservation and management.
Qualifications
- Ph.D. in Physiology, Ecology, Animal Biology, Animal Behavior, or a closely related field.
- Demonstrated hands-on experience conducting fish physiology experiments and interpreting physiological data.
- Experience in experimental design, planning, and project coordination, including the ability to meet research objectives and deadlines.
- Strong statistical and analytical skills, including proficiency with R or comparable statistical software.
- Strong organizational, interpersonal, and problem-solving skills, with the ability to work independently and collaboratively.
Preferred Qualifications
- Fish physiology: Experience with physiological techniques such as swimming performance (Ucrit), thermal tolerance (CTmax), and physiological stress measurements.
- Fish behavior: Experience designing behavioral experiments and using behavioral analysis software (e.g., EthoVision).
- Field research: Experience with fish handling, cage deployments, boat-based fieldwork, and small-boat operation.
- Salmonid research: Previous experience working with salmonids, particularly Chinook salmon, including fish husbandry and experimental handling.
- Scientific productivity: Strong publication record in peer-reviewed journals, demonstrating scientific independence and effective communication of research findings.
- Research leadership: Experience independently managing research activities, troubleshooting experimental challenges, and mentoring undergraduate students or research assistants.
- Environmental toxicology: Previous experience would be an asset.
Salary and Appointment
Salary and benefits will be consistent with UC Davis policies and commensurate with qualifications and experience.
Application Requirements
Interested candidates should submit:
- Curriculum Vitae (CV), including publications, presentations, and relevant laboratory and field research experience.
- Cover letter (1–2 pages) describing their research background, relevant technical expertise, professional interests, and motivation for applying.
- Contact information for three professional references familiar with their research experience and qualifications.

Search Research Engineer Jobs in CaliforniaResearch Engineer Jobs in California: Frequently Asked Questions
Which companies in California sponsor visas for research engineers?
Large technology companies such as Google, Apple, Meta, Microsoft, and NVIDIA are among the most active sponsors for research engineers in California. National laboratories including Lawrence Berkeley, Lawrence Livermore, and Sandia National Laboratories also sponsor research engineers, as do biotech firms like Genentech and Illumina in the San Diego and San Francisco Bay Area corridors. Sponsorship frequency is generally higher at companies with dedicated research divisions.
What visa types are most common for research engineer roles in California?
The H-1B is the most common visa for research engineer positions in California, as the role typically qualifies as a specialty occupation requiring at least a bachelor's degree in a relevant field such as computer science, electrical engineering, or materials science. Researchers with exceptional recognition may qualify for the O-1A. Those with advanced degrees pursuing work in the national interest sometimes pursue EB-2 NIW petitions through their employers.
Which California cities have the most research engineer visa sponsorship jobs?
The San Francisco Bay Area, including San Jose, Sunnyvale, Mountain View, and Palo Alto, has the highest concentration of research engineer sponsorship roles in California due to the density of major tech campuses and research labs. San Diego is a strong secondary market, particularly for biotech and defense-related research. Los Angeles has growing opportunities in AI, aerospace research, and university-affiliated labs at UCLA and USC.
How to find research engineer visa sponsorship jobs in California?
Migrate Mate filters research engineer jobs in California specifically by visa sponsorship availability, saving you from applying to roles that won't support international candidates. The platform surfaces positions from employers with documented sponsorship history in this role category. Searching by state and role on Migrate Mate helps you focus on California-based research engineering openings where H-1B or O-1 sponsorship is a realistic part of the hiring process.
Are there state-specific factors research engineers should know about sponsorship in California?
California's prevailing wage requirements under Department of Labor rules apply to H-1B positions statewide, and wages in the Bay Area and San Diego markets are among the highest in any U.S. metropolitan area, which affects the LCA wage level your employer must certify. Many California research engineer roles are affiliated with UC system or Stanford research pipelines, meaning candidates transitioning from OPT or CPT are a common hiring profile at these employers.
What is the prevailing wage for sponsored research engineer jobs in California?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
