Genetic consequences of habitat fragmentation and human-induced gene flow in a recreationally important fish species

The Bernos F.I.S.H. lab at the University of Vermont (United States) is seeking a motivated graduate student for an MSc or PhD research assistantship focused on population genomics and landscape genetics of Smallmouth Bass, with an anticipated start date of September 2026 (with opportunities to start earlier).

This project will use genomic data to characterize the population structure of Smallmouth bass in Lake Champlain, with a particular focus on evaluating the effects of habitat fragmentation and anthropogenic activities on genetic structure. Lake Champlain is a highly fragmented lakescape where connectivity is shaped by both natural geological features (islands) and human-built barriers (causeways). Because Lake Champlain is a worldclass destination for recreational Bass fishing, there is also interest in understanding how fishing and management practices might influence the evolutionary trajectories of Bass population. Therefore, this project will also have opportunities to explore genotype-by-environment associations and fishery-induced evolution. The successful student will begin at the University of Vermont in the fall 2026 semester (negotiable start date). Fieldwork will involve sampling Smallmouth bass populations throughout the lake and tributaries to collect biological data and obtain fin clips for later genetic analysis. Lab work will involve DNA extraction and library preparation. This project is a collaborative effort with VT Fish and Wildlife Department and other university partners.

Qualifications: Required: B.S. in fisheries, biology, or related field. Applicants should also have demonstrated excellent written and oral communication skills, and an ability to work independently. Interest in collaboration and enthusiasm for clear scientific communication (written and verbal) is also required. Successful candidates will have some knowledge of R, and some prior experience/exposure to molecular work and bioinformatics is preferred but not required. Applicants with experience in fish ecology, statistical & analyses of large datasets are encouraged to apply.

How to apply: If you have questions about the position or the location, please email Dr. Thaïs Bernos (thais.bernos@uvm.edu). To apply, please attach (1) a statement of interest that describes your educational and research background, as well as your research interests and how this position fits in your career goals (2) 2 pages curriculum vitae or resume, (3) contact information for two professional references, and (4) unofficial transcripts compiled in a single PDF and save as ‘LASTNAME_SmallmouthBass.PDF’. Please use ‘Smallmouth Bass position’ in the email subject line. Application deadline is May 1st, 2026 for full consideration. You can learn more about the Bernos F.I.S.H. Lab at https://bernoslab.wordpress.com. The position could start in the Fall or earlier during the summer.
