My research focuses on a variety of problems in biological oceanography and zooplankton ecology, particularly those related to how climate-driven environmental change interacts with biological processes to control zooplankton biogeography, diversity, community structure, and abundance. The interactions between the physical and chemical environment and zooplankton population structure, behavior (e.g., diel vertical migration), and growth ultimately control ecosystems, fish, and other upper trophic level organisms. I work on these interdisciplinary projects using a combination of field collections, laboratory experiments, and satellite data.
