Monika Roy is a third year doctoral student in UMass Amherst's environmental health sciences program. A former CRF student awardee, Monika will investigate the liver toxicity potential of the environmental chemical 3,3’-dichlorobiphenyl, or PCB-11. PCB-11 is primarily a byproduct of yellow pigment manufacturing, but is also found in sealants, resins, and other consumer products where it can eventually evaporate and be inhaled by humans. The National Institute of Health (NIH) grant is funded through the Ruth L. Kirschstein Predoctoral Individual National Research Service Award (NRSA) program, enables promising predoctoral students with potential to develop into productive, independent research scientists, to receive financial support to conduct their own dissertation research.
