Marjy Friedrichs, PhD, is a Research Professor at the Virginia Institute of Marine Science (VIMS) at William & Mary. She uses interdisciplinary mathematical models together with monitoring data to better understand how human impacts, such as changes in global climate, urbanization, and land use affect coastal water quality.


Many of Friedrichs' current modeling projects involve studying long-term historical and future changes in hypoxia and coastal acidification in the Chesapeake Bay. She has also led the development of a forecasting system that produces short-term forecasts of hypoxia and acidification metrics for the Bay, and an annual hypoxia report card to track progress towards attaining water quality standards.


Through her ongoing collaborative work with Chesapeake Bay Program managers as well as fisheries and aquaculture industry members, she continues to work to make her science relevant for Chesapeake Bay stakeholders.

Dr. Friedrichs has a BA in Physics from Middlebury College, an MS in Oceanography from the MIT/Woods Hole Joint program, and a PhD in Oceanography from Old Dominion University.
