Research Experience
Graduate Research Assistant – University of South Carolina – Columbia, SC - August 2012 - Present
●Developed techniques for the analysis of short-lived reactive species in complex environmental systems
●Employed multivariate experimental methods and statistical modeling to simulate natural aquatic matrices to explore redox cycling of transition metals and the generation of Reactive Oxygen Species (ROS) at groundwater-seawater mixing zones (oxic-anoxic interfaces)
●Designed and tested chemical kinetic models to characterize and predict the fate of ROS
●Utilized 224Ra/228Th disequilibrium based on Radium Delayed Coincidence Counting (RaDeCC) technique to assess the seawater-freshwater exchange in coastal sediments
●Served as laboratory safety officer and worked with the USC Environmental Health & Safety department to enforce lab safety and regulatory compliance of OSHA
Undergraduate Researcher – University of Colombo - August 2007 – December 2011
●Research project title - Use of sediment, water and biota as indicators of pollution in the Bellanwila-Attidiya sanctuary
●Instrumentation/Techniques: Double beam flame Atomic Absorbance Spectrometry (AAS), UV-Vis
●Analyzed water, sediment and plant samples for trace metal ion concentrations (Fe, Ni, Zn, Cu, Pb, Cd, Cr)
●Followed ASTM protocols to carry out various analytical tests (nitrate/nitrite, DO, COD and BOD) to evaluate the level of pollution in an urban reservation
Teaching Experience
Graduate Teaching Assistant - University of South Carolina – Columbia, SC - August 2012 - Present
●Taught recitation and laboratory sessions in General Chemistry I and Quantitative Analysis
●Instructed and trained undergraduate students in general to advanced laboratory techniques (UV-Vis, Fluorescence, GC-MS, gravimetric techniques, extractions, titrations, etc.)
●Responsible for grading, exam proctoring, solution preparation and lab maintenance
●Served as Course Manager for General Chemistry I
●Conducted exam review sessions for Quantitative analysis for 80+ students
