Professor Smith and his research group address the relationships among environmental quality, health, resource use, development, and policy in developing countries, with a focus on the health effects of air pollution exposure in developing countries, particularly in women and children from household air pollution due to solid fuel use. With IIT Delhi, Sri Ramachandra University, and TERI, Professor Smith recently launched the Collaborative Clean Air Policy Centre, which explores, evaluates, and compares policy options for dealing with India’s health-damaging air pollution problems of all types, including  ambient and household.
