"Joel Schwartz is professor of environmental epidemiology at Harvard University School of Public Health, his research is divided into three main areas: first, he is interested in epidemiology looking at the health consequences of exposure to pollutants (especially to lead and to air pollutants). In his air pollution works he has examined both acute and chronic effects of air pollution exposure. He has also done considerable work on health effects of ozone exposure. He is also interested in methodological questions regarding the modelling of continuous covariates in epidemiologic studies. And a third major focus of his research is on the effects of antioxidants on respiratory health. A final area of interest is the use of cost benefit analysis to make environmental decisions."
