Steven A. Cohen, DrPH, MPH, is a public health demographer and social epidemiologist at Virginia Commonwealth University.  His primary research interests include assessing the population dynamics of aging in the United States and their implications on population health, health care services, and disease patterns.  His research focuses on incorporating demographic methods to enhance epidemiological inquiry so as to better understand the proximate and distal factors impacting aging on both the population and individual levels.  Specific research projects are concentrated in three major areas: (1.) the social epidemiology of informal, family caregiving to older adults and its impacts on the health of the caregiver, (2.) modeling spatiotemporal and demographic trends in Medicare utilization in older adults, and (3.) impacts of the growing population of older adults on the distribution and welfare of the health care labor force in the US.
