Inwater Research Group Inc. was formed in 2001 by a small group of biologists to fill the need for basic population studies of wildlife in coastal habitats throughout Florida. Our organization is committed to coastal conservation through research on key coastal species and their habitats.


Ryan Chabot

Ryan graduated with a B.S. degree in Environmental Studies in 2011 and an M.S. degree in Biology in 2017, both from the University of Central Florida. He has worked extensively with sea turtles on east central Florida nesting beaches and in-water habitats as part of the University of Central Florida Marine Turtle Research Group. His graduate research focused on identifying the in-water foraging areas of adult green turtles that nest on the Archie Carr National Wildlife Refuge in Melbourne Beach, FL using chemical signatures in their tissues. Ryan joined the IRG team in 2017 and his primary interests are the intersection of sea turtle ecology and behavior, as well as using long-term data to inform science-based management and conservation decisions

Jeff Guertin

Jeff graduated with a B.S. in Biology from The George Washington University in 2005 and an M.S. in Biology from Florida Atlantic University in 2010.  During graduate school, he explored the regional differences in migratory activity by hatchling loggerhead sea turtles and the effect of reciprocal nest translocations between nests deposited on the east and west coasts of Florida. He joined the IRG team in 2010 and is interested in animal behavior and biological interactions between marine species.

Cody Mott

Cody has worked with sea turtles since 2006 on projects ranging from raising leatherback hatchlings to training a juvenile loggerhead for a documentary film. Cody’s research interests focus on animal behavior, nearshore reef ecology, and understanding the effects of anthropogenic stressors on sea turtles. He received his Bachelor’s and Master’s degrees in Biology from Florida Atlantic University (FAU). Cody worked as a Research Assistant at FAU and as a Marine Turtle Specialist for the City of Boca Raton, Florida before starting with Inwater Research Group in 2010.

Ryan Welsh

Ryan received his BA in biology from Earlham College where he gained an interest in herpetology and conservation while working with Dr. John Iverson on the Allen Cays Rock Iguana in the Exumas Islands, Bahamas.  After graduating in 2003, he began his work with sea turtles.  Ryan’s work has been focused throughout the Caribbean and the Gulf of Mexico collaborating with the National Park Service, US Fish and Wildlife Service, The Nature Conservancy, Mote Marine Laboratory and Sea Turtle, Inc.  Working with all life stages of sea turtles; Ryan has experience in research areas including mark-recapture, nest surveys, predator control, satellite tagging and rehabilitation.


Board Members

Michael Bresette- President/Director

Michael’s love for the marine environment began in his early teens during a summer class with Dr. Peter Auger studying diamondback terrapins on Cape Cod. Michael went on to attend Florida Institute of Technology in Jensen Beach, majoring in Oceanographic Technology. He has designed and implemented various projects including mangrove habitat restoration, fish mark and recapture studies, and a wetlands conservation educational program for grade school children. He began working with sea turtles in 1992. His interest in the status of marine turtles in the southern Indian River Lagoon System was the impetus for the creation of Inwater Research Group. Michael is a founding member of Inwater Research Group and as you will see below is fortunate to be surrounded by some of the brightest and most dedicated marine biologist in the field.

Jonathan Gorham, PhD.- Vice President/Director

Jonathan received a BS degree from the University of California and a doctorate in marine biology at Florida Institute of Technology. He became interested in sea turtles during the course of his dissertation research on the ecology of coral reef fishes in the Bahamas and Florida Keys. He served as lead biologist for the sea turtle conservation program at FPL’s St. Lucie power plant for 5 years. There he was involved in studies of turtles on nesting beaches and research involving open water capture of sea turtles. He is currently, the Coastal Resource Manager for Indian River County, where he manages and minimizes the impacts beach re-nourishment projects have on sea turtle habitat. He is a founding member of IRG and has taken the lead in developing methods to efficiently assess population levels of sea turtles in their near-shore habitats.

Blair Witherington, PhD.- Vice President/Director

Blair Witherington received his BS and MS in Biology from the University of Central Florida and a PhD from the University of Florida. He has conducted work on sea turtle biology and conservation within the Fish and Wildlife Research Institute and has served on numerous graduate student committees, panels, and working groups. He is an adjunct assistant professor at the University of Florida, has served as president of the International Sea Turtle Symposia, and is a member of the Marine Turtle Specialist Group of the International Union for Conservation of Nature. Blair has been appointed to the National Research Council and has authored more than 40 scientific articles, monographs, and book chapters. Blair along with his wife, Dawn, are the authors of the field guide “Florida’s Living Beaches”.
