Research & Publications

Research Summary

Dr. Breysse's research focuses on the evaluation and control of chemical, biological and physical factors that can impact health or wellbeing. In this context, his research concentrates on risk and exposure assessment. Exposure assessment research includes pollutant source characterization, exposure measurement and interpretation, development and use of biomarkers of exposure/dose/effect, and evaluating relationships between sources, exposures, doses and disease. 

His research currently includes studies on the impact of indoor and outdoor air pollution on respiratory health, with a focus on childhood asthma, chronic obstructive pulmonary disease and respiratory tract infections. Dr. Breysse also conducts second secondhand smoke exposure studies around the world in support of tobacco control policy development. 

Dr. Breysse collaborates on complex health and exposure studies around the world, including studies in Peru, Nepal, Mongolia, Columbia and India. In addition, he collaborates with colleagues in material sciences and engineering on the development of novel sensor technology using organic semiconductors.
