Dr. Lomas received his PhD in Biological Oceanography in 1999 from the University of Maryland, where he studied the nitrogen metabolism of marine phytoplankton in response to variable light, and therefore cellular energy, environments. He was a postdoctoral scholar at Horn Point Laboratory in the Harmful Algal Research Group before joining BIOS's Bermuda Atlantic Time-series Study (BATS) team in 2001. His primary interest is studying the ecological linkages between phytoplankton functional diversity and nutrient biogeochemical cycling.

Dr. Lomas is currently involved in several projects, including: examining long-term patterns in phytoplankton diversity at BATS and relationships to ocean carbon cycling; the role of winter mixing on altering phytoplankton community structure and enhancing biologically mediated carbon export; and utilization of dissolved organic phosphorus substrates by phytoplankton taxonomic groups. He is an adjunct faculty member of the Duke University Nicholas School of the Environment, where he teaches a core course in biological oceanography.
