Research Interests
Please note: Due to my administrative obligations I am not currently accepting new students  (as of Fall 2013)

My research program focuses on benthic ecology and benthic processes of estuarine and coastal ecosystems. I am interested in how nature and humans influence the structure and function of estuarine ecosystems.

With my students and other colleagues I have studied how factors such as hypoxia, benthic-pelagic coupling, climate change and population dynamics of key species regulate biodiversity and productivity of estuarine communities and food webs.  I am also interested in how organism-sediment interactions affect nutrient cycling, sediment transport and the fate of pollutants.

My work has taken me to estuarine and coastal ecosystems throughout the U.S. and Europe, including the Chesapeake Bay, Gulf of Mexico, Long Island Sound, Baltic Sea, Andaman Sea, Gulf of Thailand and coastal Korea.

In recent years I have become increasingly interested in how society, science and economics interact to influence resource management, science policy and funding for science and math education.
