Director

  • Alan Cohen, PhD

    • Associate Professor of Environmental Health Sciences (in the Robert N. Butler Columbia Aging Center)

    Alan combines expertise in aging, physiology/biomarkers, statistics, modeling, epidemiology, and ecology/evolution to generate novel insights into aging processes with population-level biomarker data. He is particularly interested in complex systems, and has produced the first empirical verification of physiological dysregulation as a driver of the aging process. He also has expertise in statistical approaches to integrating signals across large numbers of molecules to detect underlying processes, and has developed several multivariate and/or dynamic approaches to measuring health with common biomarkers. 

    Alan holds a PhD in Ecology and Evolution from the University of Missouri, St. Louis.
