The Gibson lab at UVA is hiring a postdoc to study dispersal as a parasite avoidance mechanism. Apply by mid-January: uva.wd1.myworkdayjobs.com/UVAJobs/j…. #postdoc
uva.wd1.myworkdayjobs.com
Research Associate in Biology
The Department of Biology at the University of Virginia invites applicants for a post-doctoral Research Associate position in the lab of Professor Amanda Gibson as part of an NSF-funded project. The Gibson lab is broadly interested in the evolution of avoidance versus resistance as modes of parasite defense. This project specifically tests the idea that host dispersal evolves as an escape in space from parasites, and it evaluates the downstream consequences of dispersal for the evolution of host resistance. The work makes use of the experimental tools and resources available for the model nematode C. elegans and its natural parasites. Associated projects entail evolve-and-resequencing, quantitative trait mapping, and field sampling with spatial analyses. The selected candidate will also mentor undergraduate students in independent research projects through a summer program for incoming transfer students. Find out more about the lab at https://coevolving.org. REQUIRED QUALIFICATIONS: o A PhD in Biology or a related field by the start date. PREFERRED QUALIFICATIONS: Demonstrated conceptual and technical strengths in host-parasite interactions, evolutionary ecology, evolutionary genetics, and/or dispersal biology Experience in basic lab and molecular work A strong background in experimental design, data analysis, and data management Excellent written and oral communication, demonstrated by a strong publication record, consistent with the candidate’s career stage, and presentations at conferences Demonstrated ambition, creativity, independence, and ability to work well with others Experience in and dedication to mentoring junior trainees APPLICATION PROCEDURE: Apply online https://jobs.virginia.edu/us and search for R0078709. Attach a cover letter outlining your qualifications and motivation for pursuing the position, curriculum vitae, and contact information for three individuals who can provide professional reference letters. In the cover letter, please address your fit with the qualifications above and your experience in mentoring undergraduates. Please note that multiple documents can be uploaded in the box. APPLICATION DEADLINE: Review of applications will begin on January 15, 2026. The University will perform background checks on all new hires prior to employment. Anticipated start date for this position is May, 2026, but the start date is flexible. This is a one-year appointment; however, appointment may be renewed for additional two, one-year increments, contingent upon available funding and satisfactory performance. For questions about the position, please contact Amanda Gibson, Associate Professor, at akg5nq@virginia.edu. For questions about the application process, please contact Richard Haverstrom, Academic Recruiter, at rkh6j@virginia.edu. For information on the benefits available to postdoctoral associates at UVA, visit postdoc.virginia.edu and hr.virginia.edu/benefits. The University of Virginia is an equal opportunity employer.
