Research Interests

I study marine bottom-dwelling (benthic) invertebrates and how their activities influence chemical, physical, and biological processes at the sea floor. I first became interested in benthic organisms while digging up various worms, clams, shrimp and other unusual creatures inhabiting mud flats exposed at low tide in front of his grandparent's home on Vashon Island in Puget Sound, Washington.

Although the vast majority of the earth's solid surface is covered in marine mud and benthic organisms thus inhabit the largest habitat on the earth's solid surface, there is much to be learned about the ecological and functional roles these bottom dwellers play in the ocean. An important theme in my research is "bioturbation", the effects of benthic organism feeding, burrowing, and burrow ventilation on marine sediment properties. I have studied benthic communities in Puget Sound, Boston Harbor, the North Atlantic, and the Bering Sea. My current research focus is on eelgrass in Puget Sound and how it influences and is influenced by sediment pore-water hydrogen sulfide.
