Rajendra S. Chhabra, BVSC., Ph.D., D.A.B.T., coordinates the Postdoctoral Training Program for the Division of National Toxicology Program (DNTP). The NTP is committed to attracting and training outstanding post doctoral researchers with diverse educational backgrounds and skills into the NTP program to build their careers and help create a safer world.


Chhabra provides coordination and oversight for all postdoctoral training positions within the NTP. Chhabra works closely with the trainees and their mentors to establish individualized training programs, to provide each trainee with opportunities to become familiar with all aspects of the NTP, and to follow the trainee's progress through the program and beyond.


Chhabra earned his Ph.D. in pharmacology from the University of London, England, and BVSc (a D.V.M. equivalent) from India's Vikram University. He is Diplomate, American Board of Toxicology (D.A.B.T.). His current research interests are in the field of general toxicology. This entails conceiving, planning, designing, evaluation and interpretation of animal toxicology studies to identify the potential health hazards in humans posed by the environmental chemicals. He has over 30 years of progressive experience as a lead toxicologist for a number of program-related projects or functions within the NTP. He has been invited participant to national and international meetings and has authored numerous manuscripts, reviews, technical reports, and served on the editorial board of Environmental Health Perspective for several years. He is a member of Society of Toxicology (SOT), North Carolina SOT and the American Society for Pharmacology and Experimental Therapeutics (ASPET).
