With extensive interdisciplinary/interagency collaborations, the group designs, conducts or directs studies intended to address targeted research needs by applying state-of-the-art methodology. After review of the results from these studies, follow-up research projects are undertaken to investigate mechanistic aspects of adverse effects for the select chemicals. The group publishes its findings by preparing technical reports that are peer-reviewed by the external expert panels. The toxicology research data generated is often used by the regulatory agencies to assess potential risk to the population exposed to chemicals present in the environment or workplace. The group consists of highly accomplished scientists who are often sought for their expert opinion by the national and international organizations dealing with the potential adverse effects of toxicants humans are exposed to.
