  • Ecology of tidal and inland wetlands
  • Wetland restoration
  • Botany and plant ecology

Dr. Andy Baldwin is Professor in the Department of Environmental Science and Technology. His research and teaching focus on plant and ecosystem ecology of natural and restored wetlands. He is interested in both coastal and inland wetlands, with the goal of understanding links between plant regeneration, carbon and nitrogen cycling, and global change factors (particularly sea-level rise, temperature, eutrophication, and invasive species). He teaches classes on wetland ecology and restoration, and is past President of the Society of Wetland Scientists.
