Stephen Fienberg (NAS), PhD, is Maurice Falk University Professor of Statistics and Social Science at Carnegie Mellon University. His principal research interests lie in the development of statistical methods, especially for problems involving categorical variables. Initially, he worked on the general statistical theory of log-linear models for categorical data, including approaches appropriate for disclosure, estimating the size of populations, and Bayesian approaches to the analysis of contingency tables. His research on disclosure limitation for categorical data, and on confidentiality privacy and security more broadly, has led to the creation of a new on-line journal, the Journal of Privacy and Confidentiality, of which he is editor-in-chief. Dr. Fienberg serves on the editorial board of the Proceedings of the National Academy of Sciences of the United States of America and was elected a member of NAS in 1999. He is also a fellow of the American Academy of Arts and Sciences and of the Royal Society of Canada. He has served on 29 National Research Council, NAS, and Institute of Medicine committees and panels. He chaired the Committee on National Statistics in 1981–1987 and has served as cochair of the Report Review Committee since 2012. Dr. Fienberg received a PhD in statistics from Harvard University.

William K. Hallman, PhD, is chair of the Department of Human Ecology and director of the Food Policy Institute of Rutgers, the State University of New Jersey.
