Patricia 'Tricia' Thibodeau, Ph.D.


Assistant Professor


Girard Marine Science Center 213
Biddeford Campus

I am a plankton ecologist and biological oceanographer focused on the effects of rapid climate change on phytoplankton and zooplankton populations and physiology. The major pillars of my research explore how global climate change (1) has and will impact long-term trends in plankton population dynamics and (2) has affected plankton physiology and feeding ecology. I study these themes around the world from Antarctica to the Gulf of Maine. I am also the President of the non-profit organization, Society for Women in Marine Science (SWMS), whose mission is to bring together marine scientists of all career levels to discuss the diverse experiences of women in marine science, celebrate the research done by women in the field, and promote the visibility of women in the marine science community.
