Diversity and Dynamics of Marine Bacterioplankton
Characterization of large-scale 16S rRNA gene libraries from station the Pivers Island Coastal Observatory (PICO) as well as the environmental drivers of this diversity with a specific focus on microbial responses to disturbance and stressors including ocean acidification. In collaboration with the Johnson lab at Duke and the Konstantinidis lab at Georgia Tech.
Interactions of Bacterioplankton with Marine Microenvironments
Examining changes in activity and phylogenetic affiliation of particle-attached and free-living bacteria. Investigation of the cost and benefits of co-growth for bacteria and algae with an emphasis on chemotactic aggregation of bacteria around phytoplankton cells. Phytoplankton work is in collaboration with the Rynearson lab at URI.
Microbial Responses to Emerging Pollutants
Examining the response of prokaryotic and eukaryotic microbes to additions of nanomaterial and other emerging pollutants through mesocosm and lab-based studies. In collaboration with the Center for the Environmental Implications of Nanotechnology (CEINT).
