Research Interests To further our knowledge of the biological, physical, and chemical factors, which govern the "Umwelt" of planktonic micro-crustaceans. To investigate the first principles involved in the interactions between the algae and their herbivores, and between herbivorous and carnivorous zooplankton. To research and develop new methods of investigation appropriate to the temporal and spatial scales of plankton.
