While no longer national news, the Deepwater Horizon oil spill is still impacting the ecological health of the Gulf of Mexico and the livelihoods of the communities that rely upon the gulf’s aquatic life, as Robert “Joe” Griffitt of the University of Southern Mississippi reveals. Dr. Griffitt and co-hosts Anne Chappelle and David Faulkner discuss how ecotoxicology is both an applied and a basic science, as well as how scientific discovery is not always a linear process. About the GuestRobert “Joe” Griffitt, PhD, is a Professor at and Director of the University of Southern Mississippi School of Ocean Science and Engineering. Ecotoxicology, toxicogenomics, and bioinformatics are the focus of Dr. Griffitt’s research. Specifically, his lab investigates the impacts of metallic nanoparticles in aquatic and marine ecosystems and the effects of the 2010 Deepwater Horizon oil spill on the northern Gulf of Mexico. In both cases, his lab uses a combination of molecular and whole-animal endpoints to try to assess toxicological impacts at both cellular and organism levels. Dr. Griffitt earned a BS in marine biology from the University of North Carolina Wilmington and an MS in marine science and a PhD in environmental science from the University of South Carolina. He completed his postdoctoral research at the University of Florida.
