Kristen Malecki, PhD, MPH is Professor of Environmental and Occupational Health Sciences (EOHS) at the University of Illinois at Chicago (UIC), School of Public Health, where she also serves as the EOHS Division Director. She has a PhD in Environmental Epidemiology and Health Policy and Masters of Public Health from Johns Hopkins University Bloomberg School of Public Health. She was recently appointed to the National Academies of Sciences standing committee on the “Use of Emerging Science for Environmental Health Decisions.” She uses a multi-omic approach to examine combined chemical (air pollution, water pollution), physical and social stressors, and their influence on adult chronic disease, aging and health disparities.) As a former member of the Molecular Environmental Toxicology Center at the University of Wisconsin, Madison and  her transdisciplinary work uses epigenetics, transcriptomics in both human and animals studies of the gut microbiome and to identify interim biomarkers of exposure and response to improve understanding of the biological mechanisms underlying persistent health disparities. Prior to coming to UIC, she served as the PI for the Survey of the Health of Wisconsin Cohort study in Wisconsin, a novel infrastructure for ongoing population health science research. She also maintains longstanding partnerships with state and national public health partners which has facilitated a breadth of applied public health initiatives. Before becoming an academic, she served as the lead epidemiologist for the State of Wisconsin Environmental Public Health Tracking Program. In these roles she gained extensive experience in leading and managing multi-disciplinary teams of researchers, practitioners, and policy makers in development of new approaches to addressing environmental and occupational health challenges. She currently serves as PI for the National Coordinate Center for New Cohorts for Environmental Exposures and Cancer Research (CEECR) funded by the National Cancer Institute and the National Institute for Environmental Health Sciences as well as the Researching Epigenetics, Weathering, Aging and Residential Disadvantage (REWARD) funded by the National Institutes of Aging and is a member of the Chicago Center for Health and the Environment a collaborative NIEHS funded environmental health center including partnerships between UIC and the University of Chicago.
