Suramya Waidyanatha, Ph.D. is the discipline leader for Chemistry and ADME (absorption, distribution, metabolism and excretion) and oversees the activities of the Chemistry and ADME (absorption, distribution, metabolism and excretion) Resources Group (CARG) in support of the National Toxicology Program’s mission. She designs the research needs in analytical chemistry, ADME and toxicokinetics for chemicals of interest to NTP and facilitates the use of ADME and toxicokinetic data in the design, interpretation, and reporting of NTP toxicity and carcinogenicity studies. She also manages contracts conducting ADME studies, toxicokinetics studies and analytical chemistry activities in support of the NTP toxicity and carcinogenicity studies. She serves as the NTP toxicokinetics faculty chair.

Waidyanatha’s research interests include: development, validation, and application of analytical methods to quantitate trace analytes in complex matrices; metabolism and disposition of xenobiotics and the kinetic parameters describing these processes in rodents in vivo and rodents and humans in vitro; mechanism(s) of interactions of xenobiotics and/or their metabolites with cellular macromolecules resulting in toxicity.

Waidyanatha received her B.S. (Honors) in Chemistry from University of Colombo, Sri Lanka in 1985, her M.S in Biochemistry from University of Illinois, Chicago in 1987 and her Ph.D. in Analytical Chemistry from University of Maine in 1990. She worked as an analytical chemistry resource support person for Glaxo Inc., RTP, North Carolina briefly prior to joining the School of Public Health at the University of North Carolina at Chapel Hill in 1991 as a Postdoctoral Fellow. She continued her career at the university as a Laboratory Director and then as a Senior Scientist. During her 17 years at the university, she investigated biomarkers of exposure to xenobiotics and their utility in elucidating xenobiotic metabolism and disposition which advanced her knowledge in toxicology, epidemiology and biostatistics. She joined NTP in 2008 as a staff scientist and currently holds an adjunct appointment at the University of North Carolina at Chapel Hill.

She is listed as an author in over 70 peer-reviewed research articles in scientific journals. She is a member of Society of Toxicology and American Chemical Society.
