Research Interests

Scott M. Williams, PhD, is a professor and director of the Epidemiology & Biostatistics graduate studies program in the Department of Population and Quantitative Health Sciences. He also is a professor with the Department of Genetics and Genome Sciences. Both departments are part of Case Western Reserve University School of Medicine.

Williams is an expert in the genetics of complex human disease, including the genetic risk of adverse pregnancy outcomes, hypertension, cardiovascular disease, cancers, and susceptibility to infection. An experienced population geneticist, he studies how genes, either singly or in interactions with the environment, affect disease risk in different populations.

He has also been actively involved in developing statistical analyses for genetic susceptibility to disease, including colorectal and gastric cancers. He has studied the role of genetic factors for multiple infectious diseases, including malaria and tuberculosis. His work on TB has focused on resistance to TB in HIV positive individuals. Dr. Williams also has assessed the role of environmental changes in cardiovascular risk factors in West African populations.

Williams has extensive experience in graduate education, having developed the PhD program in human genetics at Vanderbilt University and served as program director of other institutions’ PhD programs.

Williams received his PhD in biology from Washington University, St. Louis, in 1981 and his BA in political science from the University of Chicago in 1976. Before coming to Case Western Reserve University, he was a professor in the Department of Genetics, Geisel School of Medicine, Dartmouth College, where he served as founding director of the Center for Integrative Biomedical Sciences and associate director of the Institute for Quantitative Biomedical Sciences.

Williams currently serves as an editor of PLoS Genetics and Current Genetic Medical Reports, and is a member of the executive committee of the African Society of Human Genetics.

He has published more than 250 papers addressing issues of disease risk, disparity, genetic differentiation, and methods to address these from both theoretical and practical perspectives.
