Randall Wells directs the Sarasota Dolphin Research Program, the world’s longest-running study of a dolphin population.  He began studying bottlenose dolphins in Sarasota Bay, Florida, as a high school volunteer at Mote Marine Laboratory in 1970. Wells received his PhD in Biology from the University of California, Santa Cruz in 1986 and was awarded a post-doctoral fellowship from Woods Hole Oceanographic Institution.  He has worked with the Chicago Zoological Society since 1989, where he is currently a Senior Conservation Scientist, and he manages Mote Marine Laboratory’s Dolphin Research Program. Wells is a Professor of Ocean Sciences (adjunct) at the University of California, Santa Cruz, and Professor of Marine Mammal Science (adjunct) at the University Florida, through which he supervises masters and doctoral students

Wells’ current research program uses a collaborative approach to examine the behavior, social structure, life history, ecology, health, and population biology of bottlenose dolphins along the central west coast of Florida, with studies focusing on five generations of a locally resident 160-member dolphin community.  Recent research topics include the effects of human activities on coastal dolphins, such as boat traffic, fishing activities, human feeding of wild dolphins, and environmental contaminants.  Wells has served as principal or co-principal investigator for more than 150 funded marine mammal research projects.  In addition to bottlenose dolphin research, Wells has engaged in studies of the behavior of Hawaiian spinner dolphins, blue, gray, and humpback whales, ranging and dive patterns of franciscana dolphins off Argentina, the effects of industrial activities on bowhead whales, the impacts of boat traffic on manatees, and the reintroduction of captive and rehabilitated dolphins back into their native waters.

Wells has authored or co-authored 4 books, more than 148 peer-reviewed journal articles and book chapters, 66 technical reports, and 13 popular or semi-popular pieces.  He has been presenter or co-author of more than 250 presentations at professional meetings or invited public or university lectures.  Wells is President of the international Society for Marine Mammalogy.  Wells also serves on the NOAA/USFWS Atlantic Scientific Review Group, and he is past-chair of the NOAA/USFWS Working Group on Marine Mammal Unusual Mortality Events.  Wells serves on IUCN’s Cetacean Specialist Group and Reintroduction Specialist Group.
