Assistant Professor in the Department of Environmental Health

Department of Environmental Health


Broadly my research focuses on environmental and occupational risk factors of chronic diseases, including cardiovascular disease, cancer, COPD, rheumatoid arthritis, and reproductive systems. I have mainly focused my research on the effects of air pollution and traffic exposure in the general population and in workers from the railroad and trucking industries. I am particularly interested in incorporating geographic information system (GIS) technologies and spatial statistics into these fields to improve exposure assessment, control for area level confounding by factors such as socioeconomic status (SES), and to explore the geographic distributions of disease. I have primarily worked with data from large cohort studies based at Brigham and Women’s Hospital and the Harvard School of Public Health, such as the Nurses’ Health Studies (NHS, NHSII, and NHS3), the Health Professionals’ Follow-up Study, the US Railroad Workers Study, and the Trucking Industry Particle Study.


I currently co-teach two of the core courses in the EER Program’s MS curriculum, EH508 (the Environmental Exposure, Epidemiology and Risk Thesis Course) and EH263 (Analytical Methods and Exposure Assessment). Starting in the summer of 2016, I will be teaching ID215 (Environmental and Occupational Epidemiology).
