Patrick Breysse, PhD
Professor, Environmental Health Sciences
Director
Dr. Breysse's research focuses on the evaluation and control of chemical, biological, and physical factors that can impact health or well being.  This 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.  Dr. Breysse’s research focuses on air pollution health impacts with a particular emphasis on asthma.

Alison Geyh, PhD
Associate Professor, Environmental Health Sciences
Co-Investigator
Dr. Geyh's expertise is primarily on airborne contaminants, including quantifying these contaminants, identifying their sources, investigating their chemical composition, and following the routes of human exposure. Dr. Geyh is also Director of the CSA Core.

Inkyu Han, PhD, MPH
Post Doctoral Fellow, Environmental Health Sciences

Dr. Han’s research focuses on personal exposure to toxic compounds and biomarkers of external and internal dose. In Project 2 of the JHPMRC, he is working with Drs. Breysse and Geyh on exploring the relationship between exposure to ambient particulate matter (PM) and a range of health outcomes through a detail analysis of ambient PM.
