Research Interests

Dr. Field's is a zooplankton ecologist. The Fields' laboratory studies the role of zooplankton (particularly copepods) in transferring organic matter through the food web and in mediating bio-geochemical cycling in the oceans. Our approach is to understand how the mechanisms that occur at the level of the individual animal drive regional and global scale distribution patterns in zooplankton. This work incorporates general data of zooplankton ecology (classical grazing experiments, egg production and developmental rates) as well as data from small-scale fluid mechanics, neurophysiology and animal behavior.
