Microbial oceanography: the role of marine phytoplankton in the ocean’s “metabolism”; the cyanobacterium Prochlorococcus as a model to study marine ecology from the genome level to the whole ocean.
Environmental organic chemistry: phase exchanges and transformation processes; the modeling of fates of organic pollutants; the roles of colloids and black carbons; and passive sampling for site evaluation.
Earth’s biochemical cycles and development of novel observational systems to study those cycles; methods to interact sustainably with the natural environment.
Physical mechanisms which affect the transport and fate of contaminants and nutrients in surface water systems; wetland hydrodynamics, vegetated flow dynamics, and lake physics.
Exploration of structure-function relationships in microbial communities using quantitative molecular approaches, genomics, physiology, and modeling.
Physical ecology of microorganisms; microscale transport phenomena; microfluidic experiments to understand how physical forces and chemical signals shape the behavior of marine microorganisms.
Microbial oceanography: study of the relationship between the structure of microbial communities and their function using molecular biology, genomics, and genetics.
