Larry (Laurence) Madin is a senior scientist and the executive vice president and director of research at the Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Massachusetts. He was previously the chair of the WHOI Biology Department and director of the Ocean Life Institute. His main research interests are in the biology of oceanic and deep-sea zooplankton. He was among the first biologists to use scubas and submersibles to study oceanic plankton in the early 1970s. Some of his recent research has been on the population dynamics and biogeochemical effects of salp blooms in the Antarctic and elsewhere, distribution of macroplankton and fishes in the Arabian Sea, biodiversity of oceanic plankton in the Sargasso Sea, and development of new instrumentation for sampling and exploration. Madin received his AB degree from the University of California, Berkeley, and his PhD from UC Davis.
