معرفی
J. Tim Dvonch is an Associate Professor and Associate Chair in the Department of Environmental Health Sciences at the University of Michigan School of Public Health. His research focuses on exposure assessment and health effects of environmental pollutants, particularly air pollution, with emphasis on chemical composition of airborne particulates and source identification.
Dr. Dvonch earned his academic degrees from the University of Michigan:
- PhD in Environmental Health Sciences (1998)
- MS in Environmental Health Sciences (1994)
- BS in Chemistry (1992)
His expertise spans laboratory development and field evaluation of exposure assessment methodologies for air pollutants, including mass, number, and chemical composition of ambient particles at community, micro-environmental, and personal levels. He investigates health impacts of air pollution on vulnerable populations, exploring relationships between pollution exposure and adverse outcomes like respiratory/cardiovascular diseases. His work integrates atmospheric transport of toxicants across environmental systems and addresses socio-economic disparities in pollution-related health risks.
Analysis of Dr. Dvonch's recent publications reveals three dominant research thrusts: (1) Development of wearable sensor technologies for personalized aerosol exposure monitoring, (2) Health effects studies of PM2.5 on respiratory/cardiovascular systems with focus on vulnerable subpopulations, and (3) Advanced source apportionment techniques using mercury isotopes and chemical speciation. His 2022-2025 work notably expanded into wastewater-based epidemiology for pathogen surveillance during the SARS-CoV-2 pandemic.
Dr. Dvonch leads significant research initiatives including the Wearable Microsystem for Continuous Personalized Aerosol Exposure Assessment (collaborating with UM, MSU, and University of Missouri), the SEWER Network for campus pathogen detection, and contributions to the Michigan Center for Lifestage Environmental Exposures and Disease. His projects emphasize community engagement and interdisciplinary approaches to address environmental health disparities through the Community Engagement Core.
He actively collaborates with research teams across the University of Michigan, Michigan State University, and University of Missouri, focusing on translating exposure science into actionable public health interventions. His work bridges laboratory innovation with real-world community applications in environmental health risk assessment.
