Bio:  Dr. Rumbold earned his Ph.D. in Marine Biology and Fisheries from the University of Miami’s Rosenstiel School of Marine and Atmospheric Science in 1996. As part of his Ph.D research, he developed bioassays using early-life stages of various reef species and documented toxicity of substances concentrating at the sea surface microlayer. At the same time, he was part of a team investigating pesticides and polycyclic aromatic hydrocarbons (PAH) concentrating in coral reef species of the Florida Keys. He trained in PAH source fingerprinting at Bermuda Biological Station using bivalves collected from the Arabian Gulf after the first Gulf War. In 1997, he was awarded a U.S. EPA Environmental Science & Engineering Fellowship at the National Center for Environmental Assessment in Washington, DC. From 1998-2006, he served as Senior- and later Lead-Environmental Scientist for South Florida Water Management District coordinating all mercury monitoring and research. In 2006, Dr. Rumbold joined the faculty of Florida Gulf Coast University, where he is currently a professor of Marine Science. He is currently actively researching the fate and transport of methylmercury across the south Florida landscape and the lingering effects of the Deepwater Horizon Macondo Well blowout on plankton and neuston in the northern Gulf.
