Professional Summary
Dr. Dvonch's work focuses on the exposure assessment, source identification, and health effects of air pollutants. He obtained a B.S. in Chemistry in 1992. In 1994, he earned an M.S. in Environmental Health Sciences, and subsequently a Ph.D. in Environmental Health Sciences in 1998. Dr. Dvonch serves as Center Exposure Assessment Scientist for the Michigan Center for the Environment and Children's Health, and collaborates on several other large multi-disciplinary projects focused on environmental exposures and their related effects on health.

Research Interest & Projects
Dr. Dvonch's research interests and experience broadly reside in the exposure assessment, source identification, and health effects of air pollutants. For exposure assessment, his specific interests are in the laboratory development and 'real-world' field-evaluation of methodologies and techniques for improved exposure assessment to air pollutants. These primarily include the mass, number, and chemical composition of ambient particles for exposure assessment at the community, micro-environmental, and personal level. His interests in the application of these methods include source identification and apportionment of the pollutants through the use of receptor models. Further, Dr. Dvonch collaborates on several studies looking at the health effects of well-characterized exposures, both through controlled pollutant exposure studies (animals and humans) as well as population-based epidemiological investigations, using biological risk markers and outcomes including but not limited to respiratory and cardiovascular disease.
