Katherine M Keyes, PhD, MPH

Katherine M. Keyes is Assistant Professor of Epidemiology at Columbia University's Mailman School of Public Health. She received her doctorate in Epidemiology from Columbia University in June of 2010, after completion of her MPH degree in 2006. Katherine's work focuses on age, period, and cohort effects in the incidence of autism diagnoses. Katherine's prior research has focused on the epidemiology of alcohol and drug problems in both adults and adolescents, with empirical research documenting a narrowing gender gap in the prevalence and course of alcohol abuse and dependence over time. She has also examined methodological issues in age-period-cohort effect estimation for common health outcomes, including obesity, breast cancer, and substance disorders. Her work has highlighted and extended several existing age-period-cohort methods, most notably including the median polish method and multi-level modeling for age-period-cohort research questions.
