Joseph Lee Rodgers earned his Ph.D. in Quantitative Psychology, with a minor in Biostatistics, from the University of North Carolina at Chapel Hill in 1981. He worked at the University of Oklahoma from 1981-2012, where he is George Lynn Cross Research Professor Emeritus. He joined the Quantitative Methods program at Vanderbilt in fall, 2012. He has held visiting research and teaching positions at Ohio State, University of Hawaii, UNC, Duke, University of Southern Denmark, and Penn. Dr. Rodgers has won both teaching and research awards, including the 1985 AMOCO OU Outstanding Teaching award, the 1997 OU Regents Outstanding Research award, and a Presidential Professorship at OU from 2000-2004. He has been president of four professional societies: the Society for the Study of Social Biology; Division 34 (Population and Environment) of the American Psychological Association; the Society of Multivariate Experimental Psychology; and Division 5 (Quantitative and Qualititative Methods) of the APA. He was the editor of Multivariate Behavioral Research from 2006 to 2011.
His primary research focus involves building mathematical models of human behavior, with substantive interest in adolescent transition behaviors including smoking, drinking, delinquency, and sexual behavior. He also has substantive interest in human reproduction and fertility. The modeling approaches he uses include behavior genetic models, epidemiological models, and nonlinear dynamic models. He is currently PI on a three-year NIH project to develop biometrical/behavior genetic linkages (i.e., kinship links) and models to support research using the National Longitudinal Survey of Youth data.
