College of Marine Science
University of South Florida
Utilization of biogeochemical indicators to interpret past events that have impacted various marine, estuarine and freshwater environments. Employing state-of-the-art analytical techniques to examine the distribution, behavior, transport and retention of man-made and naturally occurring radionuclides in Puerto Rico, Southwest Florida and Savannah (Georgia) area inland and coastal ecosystems.
Facilitating the advancement and professional development of students representing diverse socioeconomic, cultural, gender, racial and academic backgrounds.
