Cohen Lab on Aging, Systems and Statistics

People

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.

Current lab members

  • Kamaryn Tanner, PhD

    • Associate Research Scientist

    Kamaryn joined the Cohen lab in August 2023 and holds a Ph.D in biostatistics from the London School of Hygiene and Tropical Medicine. In addition to performing statistical analyses, she is responsible for our database of cohort studies. She has expertise in clinical prediction models, dynamic prediction, survival analysis, mediation analysis, and ensemble machine learning methods. She also has extensive experience in business and management before completing her Ph.D.
