Jean Opsomer

Vice President; Statistical Fellows Committee Co-Chair

Jean Opsomer, Ph.D., is a senior statistician with 25+ years of experience applying statistical methods to answer research questions. He is currently responsible for the statistical methodology of several large-scale Westat survey projects. He has served on 6 panels of the National Academies of Sciences, Engineering, and Medicine and is a current member of the Statistics Canada Advisory Committee on Statistical Methods. He is the Chair of the Survey Research Methods Section of the American Statistical Association and Associate Editor for Survey Methodology. He is also Adjunct Professor in the Department of Mathematics at the University of Maryland, College Park.

Previously, Dr. Opsomer was a faculty member in the Departments of Statistics at Colorado State University and Iowa State University. The author or coauthor of 80 peer-reviewed articles, he has developed statistical methods for flexible model building, variable selection, and evaluation, with an emphasis on semiparametric and hierarchical modeling and statistical data integration. He is a Fellow of the American Statistical Association and the Institute of Mathematical Statistics and an Elected Member of the International Statistical Institute. He is the recipient of the Carver Medal of the Institute of Mathematical Statistics and the Cox Award of the Washington Statistical Society.

In recognition of his contributions to the field, Dr. Opsomer has been named a Westat Senior Statistical Fellow and co-chairs the Statistical Fellows Committee, which provides consultation on important survey statistics issues and addresses recent advances in applied statistics.
