My research interests encompass the effects of water flow and sediment movement on the plants and animals of the seafloor:

• Deposit- and suspension-feeding by marine benthos in relation to near-bottom flow and sediment transport, with particular interest in the responses of marine polychaete worms
• Role of submarine groundwater discharge in distributions of sandflat infauna and biological productivity
• Distribution and formation of temperate worm-reef communities and utilization of these hard-bottom habitats by motile invertebrates, including non-indigenous species

Other research interests include:

• Sampling, experimental design and flow instrumentation in laboratory and field studies of benthic habitats
• Novel methods for data analysis and image processing for rapid benthic sampling in response to natural or man-made disturbances
• Significance of biogenic structure in the trophodynamics, ecological structure and functioning of marine communities

Identification and Acquisition of Historical Benthic Survey Data from the Delaware Bay: Reconstitution, archiving and creation of a database of the estuarine distribution of over 400 species sampled in the 1950's from Delaware Bay. Collection also includes over 2100 reference specimens suitable for taxonomic study. Support provided by the Partnership for the Delaware Estuary.

Benthic Assessment of Pasture Point Restoration Project at the James Farm Ecological Preserve. Supported by Delaware’s Center for the Inland Bays and the Environmental Protection Agency.

Sandbuilder worm, Sabellaria vulgaris, reefs along the Delaware Bay coastline: Sediment stability and formation of temperate worm reefs: experimental studies with the sandbuilder worm Sabellaria vulgaris in Delaware Bay and significance of biogenic structure as benthic habitat. Prior support by the US Army Corps of Engineers.

Jill R. Brown, Ph.D. Student, Current Research Project: The settlement and life-history of the sandbuilder worm and the resulting formation of intertidal reefs in the Delaware Bay. Supported by National Estuarine Research Reserve Fellowship from the St. Jones Delaware NERR program and NOAA.
