Current Research

My work focuses on how spatial and temporal dynamics are created in pelagic marine ecosystems and the effects these dynamics have on interactions between organisms. I use a variety of field and laboratory acoustic techniques, optical methods, and behavioral modeling to investigate the effects of heterogeneity on predation and competition in the ocean. For example, as part of an ongoing collaborative effort, I am investigating the interaction between mesopelagic micronekton, zooplankton, and physical oceanography to understand both the forces driving diel migration and the consequences of this migration on community structure and nutrient cycling. To examine the proximate and ultimate reasons for responses to heterogeneous resource distribution, I am examining the effects of the micronekton layer’s migration on a variety of its predators.
