Research interests: My research involves the utilization of biogeoChemical indicators to interpret past events that have impacted various marine, estuarine and freshwater environments. Employing state-of-the-art analytical techniques, my group is currently examining 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.

In addition to conducting aquatic science radiogeochemistry investigations, I also participate in several activities designed to facilitate the advancement and professional development of students representing diverse socioeconomic, cultural, gender, racial and academic backgrounds. Some of my most recent activities include directing the Minorities Striving and Pursuing Higher Degrees of Success in Earth System Science Initiative (www.msphds.org), co-directing the USF College of Marine Science OCEANS GK-12 Fellowship Program (http://www.marine.usf.edu/education-and-outreach/GK12/index.php) and serving as a member of the US National Science Foundation Advisory Committee on Environmental Research and Education (http://www.nsf.gov/geo/ere/ereweb/advisory.cfm), American Geophysical Union Diversity Subcommittee, American Society of Limnology and Oceanography Education Subcommittee, International Safe Water Conference Steering Committee, and Digital Library for Earth System Education Annual Meeting Planning Committee.
