Areas of Specialization
Research
Biological, physical and bio-physical control of plankton ecology and plankton patch dynamics; development of theoretical and numerical models of the underlying processes at both small and mesoscale; development of instruments and sampling techniques to simultaneously quantify controlling biological and physical structure and processes; development of inverse techniques for extraction of physical, optical and biological dynamics from field data. I have a highly interdisciplinary program that is focused on biological-physical interactions and plankton patch dynamics.Students
