Dr. Chris Gennings is Director of the Division of Biostatistics and Research Professor in the Department of Environmental Medicine and Public Health at the Icahn School of Medicine at Mount Sinai and holds a secondary appointment as Research Professor in the Department of Population Health Science and Policy. Prior to joining Mount Sinai in 2014, Dr. Gennings held positions at the Virginia Commonwealth University, including as Professor in the Department of Biostatistics and Director for the Research Incubator for the Center for Clinical and Translational Research.
An expert in mixtures statistics, Dr. Gennings has been actively engaged in the field for more than 30 years. Her research interests have focused on design and analysis methodologies for studies of chemical mixtures. This has included methods for both toxicology and epidemiology/clinical studies. Recent work includes development of a body burden index with empirically derived weights linked to health outcomes; development of a holistic measure of wellness using biomarkers of effect; development of a nutrition index; development of weighted quantile sum (WQS) regression – a method that is robust to confounding concerns based on complex correlations among exposure to environmental mixtures; and the development of tests for sufficient similarity, a novel approach that complements current cumulative risk assessment methods and does not require the default assumption of additivity.
At Mount Sinai, Dr. Gennings serves as Deputy Director of the Children’s Health Exposure Analysis Resource (CHEAR) Data Center and as its Director for the Statistical Services and Methods Development Resource, which provides multi-disciplinary expertise in statistics, epidemiology, and bioinformatics for collaboration within the broader children's environmental health research community. Dr. Gennings is also Deputy Director and Director of the Pilot Project Resource of the Mount Sinai Transdisciplinary Center on Early Environmental Exposures, where researchers are studying the health impacts of chemical, genetic, nutritional, and social exposures and the interactions among them.
Dr. Gennings currently serves as Vice-President Elect of the Society of Toxicology’s Mixtures Specialty Session and as a Member of the EPA Board of Scientific Counselors’ Chemical Safety for Sustainability Subcommittee.
