Primary Interests

Jynessa is a research scientist in the Department of Environmental Conservation, based full-time at the Gloucester Marine Station. She works with integrative fisheries sciences and human dimension of fisheries, engaging local communities and fishing industry partners using participatory research tools; evaluation of management strategies and impacts on fisheries and livelihoods, and initiatives to enhance resources conservation, sustainability, and resilience. Her previous work includes coastal fisheries research in Florida and small-scale fisheries in the Brazilian Amazon.

Current Projects

  • Developing a blueprint for a seafood system incubator and transdisciplinary research programs in the University of Massachusetts.
  • A socio-economic investigation engaging stakeholders in the development and evaluation of an alternative bait in the Gulf of Maine lobster fishery.
  • Amazon dams network: advancing integrative research and knowledge on social-ecological systems transformed by hydroelectric dams.
