Education

Ph.D. in statistics, Pennsylvania State University; B.S. in mathematics, economics, Wheaton College

Overview

Joshua Snoke is a statistician at RAND. He researches statistical data privacy and confidentiality, algorithmic fairness, and workforce development.

He has expertise broadly in privacy and has published technical papers and policy reports on topics such as synthetic datasets, model estimation across multiple databases, and differentially private algorithms. His main focus concerns evaluating practical applications of privacy implementations to identify technologies which increase access to data while maintaining privacy and confidentiality.

Outside of privacy, he works on algorithmic fairness and is currently working on applying these ideas to applications in the Department of Defense (DoD) and healthcare. He also works on evaluating programs and institutions for workforce development. He focuses on DoD and DHS manpower and personnel questions, such as evaluating recruitment and promotion strategies, evaluating predictors of success in enlisted personnel, and evaluating barriers to diversity in the workforce.

His work, both privacy related and otherwise, has involved a variety of administrative and survey data, such as from the U.S. Census Bureau, the Internal Revenue Service, the UK Administrative Data Research Network, the U.S. Army Recruiting Command, and the American Educator Panels. His broader methodological interests include estimation, model selection, non-parametric modeling and classification, machine learning, and causal inference.

He received his Ph.D. in statistics with a graduate minor in social data analytics from the Pennsylvania State University. He received his B.S. in mathematics and economics from Wheaton College.
