To foster marine and coastal conservation through integrated research and education.
Michael Bresette – Executive 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 the 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 biologists in the field.
Jeff graduated with a B.S. in Biology from 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 Florida’s east and west coasts. He joined the IRG team in 2010 and is interested in animal behavior and biological interactions between marine species.
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.
Rebecca received her Bachelor of Science degree in Wildlife Ecology and Conservation from the University of Florida in 2005. After school, she began as a K-5 classroom teacher, eventually moving to informal education where she could combine her two greatest interests: science and education. Since 2014, Rebecca has spearheaded programs at Inwater Research Group, creating equitable and experiential education initiatives for students across the world. She firmly believes the future of conservation is kids, and uses sea turtles as a conduit to bring STEM alive in the classroom. Rebecca now serves as our Director of Education.

Llewellyn Ehrhart, PhD.
A loving tribute to our beloved board member. Dr. Ehrhart was a vertebrate zoologist whose research program focused on reproduction, population biology, ecologic geography, and conservation biology of marine turtles. He was awarded the Carnegie Foundation’s Florida Professor of the Year in 2003 and was a professor Emeritus at the University of Central Florida. His most recent research involved the characterization of juvenile and sub-adult sea turtle populations in coastal lagoons and over near-shore reefs, as well as long-term studies of nesting beach productivity. He was broadly interested in herpetology and mammalogy, particularly the distribution, ecology, and conservation of Florida amphibians, reptiles, and mammals. He served as Team Leader of the Southeastern Region Loggerhead and Green Turtle Recovery Team.
