Lead PI for the VCR LTER, Director of ERI, Professor

My research focuses on the effects of environmental change, particularly climate change, land-use change, and species invasions on coastal marine ecosystems. For the last 20 years, my group has studied seagrass restoration and resilience in the Virginia Coast Reserve LTER. We are especially interested in ‘blue carbon’ sequestration in coastal habitats and the impacts of marine heatwaves on seagrass ecosystems. In addition to Virginia’s Eastern Shore, my team has worked in New England, Florida, Bermuda, Denmark, New Zealand, and Mozambique. Much of my work involves interdisciplinary collaborations with partners in oceanography, geomorphology, hydrology, economics, engineering, ethics, religious studies, law, architecture, and data science. These studies focus on climate change and on the resilience of ecosystems and communities, especially in the context of decisions for equitable climate mitigation and adaptation.
