Man Kit (Karlo) Lei is an assistant professor in the Department of Sociology, and is affiliated with the Center for Family Research at UGA. Dr. Lei’s research interests include the social determinants of health and illness, sociology of aging, social epidemiology, criminology, and advanced quantitative methods and measurements. He has pursued three interrelated lines of research. First, his research focuses on understanding the impact of the social environment on biological mediators, and the way that social stressors and supports lead to health outcomes for members of minority groups. His second line of research focuses on contributions of the social environment to biological aging to better understanding how the social environment may accelerate or slow down the biological aging process. His third avenue for scholarly inquiry focuses on developing and utilizing innovative quantitative methods to better examine health-related outcomes and rate of biological aging.
