Suramya Waidyanatha, Ph.D., is a supervisory biochemist and leads the chemistry and ADME (absorption, distribution, metabolism and excretion) Resources Group (CARG) in the Division of Translational Toxicology (DTT). She designs the research needs in analytical chemistry, ADME and toxicokinetics and facilitates the use of corresponding data in the design, conduct, interpretation, and reporting of toxicology research data in peer reviewed manuscripts and government reports. Waidyanatha also administers and monitors contracts conducting ADME studies, toxicokinetics studies, and analytical chemistry activities in support of toxicology research at DTT.
Waidyanatha received her B.S. (Honors) in Chemistry from University of Colombo, Sri Lanka and her M.S in Biochemistry from University of Illinois, Chicago. She received her Ph.D. in Analytical Chemistry from University of Maine prior to joining the School of Public Health at the University of North Carolina at Chapel Hill as a Postdoctoral Fellow. She continued her career at the University of North Carolina as a Laboratory Director and a Senior Scientist where she investigated biomarkers of exposure and effect to xenobiotics. Waidyanatha joined DTT in 2008 as a chemist. She is listed as an author in over 100 peer-reviewed manuscripts and government reports.
