GMRI is currently seeking applicants for a 2-year postdoctoral researcher position to conduct research on climate-ecosystem interactions, fisheries dynamics, and coastal ecosystem ecology in the Gulf of Maine. The postdoctoral associate will work under the supervision of Dr. Graham Sherwood (Fisheries Ecologist) and collaborate with a team of scientists at GMRI and staff at the Quahog Bay Conservancy (QBC; to examine the impacts of anthropogenic change on coastal living marine resources in Maine. The successful candidate will be responsible for taking part in, and synthesizing results from, a long-term (10 year) coastal monitoring program known as CBASS ( which will involve field work (beach seining, hook-and-line sampling, and eDNA sampling), data management, quantitative analyses of fish community dynamics, quantitative spatio- temporal and cross-trophic syntheses, and mentoring undergraduate students during the summer at QBC.

The start date is June 1, 2023 or earlier. The position will be located primarily at GMRI ( in Portland, ME; summer months (June – August) will be spent in residence at QBC (Harpswell, ME; about a 45 min drive from GMRI).

  • Synthesize historical cross-trophic time series data and relate patterns to physical, biological, and ecological changes in the region.
  • Organize and lead field sampling effort that includes but is not limited to physical water measurements, beach seining (for littoral and juvenile fish and invertebrates), hook-and-line sampling (for groundfish), and water sampling for eDNA.
  • Mentor undergraduate summer interns (4-6) at QBC during the summer (June – August).  
  • Manage the CBASS-derived data,

  • Experience with field work including sampling techniques (e.g., beach seining, fishing, eDNA sampling), small boat operation, and the ability to work off hours and in variable conditions as needed.
  • Demonstrated experience and fluency in relevant programming languages (e.g., R).
  • Strong written and oral communication skills, as evidenced through publications in the peer reviewed scientific literature and presentation of results to a variety of audiences.
