WSC Workshop Leaders


The workshop is taught by five faculty members, who are leading scholars in the field of within-study comparisons:

  • Thomas D. Cook, IPR/Northwestern University
  • William Shadish, University of California, Merced
  • Peter Steiner, University of Wisconsin-Madison
  • Coady Wing, University of Illinois at Chicago
  • Vivian Wong, University of Virginia

Thomas D. Cook, IPR/Northwestern University

Thomas D. Cook is a professor of sociology, psychology, and education and social policy. He is the Joan and Sarepta Harrison Chair in Ethics and Justice and an IPR fellow at Northwestern University. He is best known for his work on the theory and practice of the design and analysis of various forms of quasi-experiments. He has published heavily on threats to validity and enumerating threats to internal validity and external validity in particular, on regression discontinuity studies, on interrupted time series work, and on various forms of individual- and group-level matching. He has authored or co-authored 10 books and about 100 articles on these topics, including Quasi-Experimentation: Design and Analysis Issues for Field Settings (with Donald Campbell, 1979) and Experimental and Quasi-Experimental Designs for Generalized Causal Inference (with William Shadish and Donald Campbell, 2002).

His current research interests include experimental and quasi-experimental design, the empirical study of methodological issues, and the methodology and practice of meta-analysis. He is the author of Experimental and Quasi-Experimental Designs for Generalized Causal Inference (with Thomas D. Cook and Donald Campbell, 2002), Foundations of Program Evaluation (with Thomas D. Cook and Laura Leviton, 1990), ES: A Computer Program and Manual for Effect Size Calculation (with Leslie Robinson and Congxiao Lu, 2000), and over 140 articles and chapters. Read full bio.

Peter Steiner, University of Wisconsin-Madison

Peter Steiner is an assistant professor in the department of educational psychology at the University of Wisconsin-Madison. His research program focuses on methodological questions about the causal inference with experimental and quasi-experimental designs, including PS-matching designs, regression-discontinuity designs, and interrupted-time-series designs.
