Associate Professor of Environmental Health Sciences, Chair in Biological Complexity and Healthy Longevity

Dr. Cohen is interested in understanding how our bodies maintain dynamic equilibrium – how evolution has shaped networks of biological and physiological mechanisms that keep us in balance across changing conditions. This understanding can lead to metrics of equilibrium that are more integrative that standard molecule-by-molecule, and that could serve as a basis for understanding health, aging, and longevity across individuals, populations, and species. I rely largely on epidemiological data (or similar data in other species) to understand how networks of biomarkers change over time.
