Research and Teaching Interests

I am a marine biogeochemist. I conducted my M.S. work on animal-sediment interactions, and my dissertation and post-doctoral work on the function of permeable coral reef sands as intense natural bioreactors. My team's current research activities revolve around coastal biogeochemistry and focus on sandy shores, the estuaries and marshes behind them and the coastal ocean in front of them. We investigate how physical, geological, chemical and biological characteristics and processes interact to affect how these settings function and exchange matter. We are especially interested in how human activities affect and are affected by these natural processes, for example by eutrophication, hypoxia, acidification, and coastal engineering interventions such as channel realignment and beach nourishment. My research is intricately connected to the courses I teach, which include introduction to marine science, marine chemistry, environmental chemistry, and coastal and marine biogeochemistry, with an interdisciplinary framework that includes the nexus of science and society.
