Postdoctoral research position: Aquatic Toxicology (Dept of ETOX at UC Davis) (JPF03721)

Posted: August 31, 2020

The Department of Environmental Toxicology at the University of California, Davis (UCD) has an opening for a postdoctoral researcher in aquatic toxicology who will work under the leadership of Dr. Ron Tjeerdema (Professor of Environmental Toxicology and Executive Associate Dean, CA&ES) and Bryn Phillips (Laboratory Director, Marine Pollution Studies Laboratory). MPSL has been conducting applied toxicology research and monitoring in watersheds, estuaries and coastal waters for over 35 years. The laboratory has a rich history of varied projects (http://www.granitecanyon.org/research-projects.html) that include marine bioassay protocol development, toxicity identification evaluation methods development, oil dispersant research, local and statewide toxicity and contaminant monitoring, and development of treatment systems to reduced toxicity and contaminants in urban and agricultural runoff.

The successful candidate with lead efforts to continue a statewide monitoring pilot project to augment the current Stream Pollution Trends Monitoring Program (SPoT https://www.waterboards.ca.gov/water_issues/programs/swamp/spot/). SPoT currently monitors sediment toxicity and chemical contamination at 90 stations statewide.  The program began in 2008, and has determined clear links among urban land use, sediment pesticide concentrations, and toxicity to the amphipod Hyalella azteca and the midge Chironomus dilutus.  SPoT measures sediment toxicity using standard U.S. EPA methods for amphipods and midges, and typically measures sediment contaminants using standard GC/MS and LC/MS methods. The proposed pilot project is expanding on SPoT’s list of monitoring tools to include some form of effects-based tools and non-target chemical analysis to investigate links between sediment toxicity and chemistry, and unknown bioactive contaminants including pesticides and other CECs.


50%: Laboratory Participation and Eventual Management

  • Participate in routine activities related to SPoT and other projects to gain knowledge of daily activities with the goal of managing personnel and projects. Level of participation will depend on level of experience with activities. This will include field sampling and all aspects of laboratory toxicity testing.
  • Become familiar with laboratory infrastructure and participate in maintenance activities.

25%: SPoT Pilot Project Administration

  • Conduct behavioral assays in cooperation with other UC Davis researchers to determine toxicity of extracts produced by non-target analyses.
  • Attend project meetings.
  • Prepare reports and manuscripts for peer-reviewed publication

25%: Develop and pursue new research directions related to use of effects-based tools in environmental monitoring, as well as pursue new possibilities for laboratory research and monitoring.

  • Participate in grant and contract preparation
  • Present results at conferences and publish results in peer-reviewed journals

Minimum Qualifications:

  • Ph.D. in Environmental Toxicology (or related field) or equivalent is required with ample experience in aquatic toxicology laboratory by start date
