Andrew D. Martin

Andrew D. Martin serves as the Chancellor of Washington University in St. Louis, a position of significant academic leadership overseeing the entire university. Prior to becoming Chancellor, he was a distinguished faculty member with expertise in judicial politics, quantitative political methodology, empirical legal studies, and applied statistics. His scholarly work has significantly impacted the understanding of U.S. Supreme Court decision-making processes.

Dr. Martin earned his PhD in Political Science from Washington University in St. Louis in 1998 and completed his undergraduate studies at The College of William and Mary, where he received an AB in Mathematics and Government in 1994 (cum laude, high honors). His academic journey reflects a strong foundation in both quantitative methods and political science, which has informed his influential research career.

Chancellor Martin's research focuses on judicial behavior, particularly within the U.S. Supreme Court, with attention to the ideological dimensions of judicial decision-making. He has pioneered methodological approaches to studying judicial behavior, developing sophisticated quantitative techniques to analyze court decisions. His work bridges political science and legal studies, creating a robust empirical foundation for understanding how courts function within the constitutional system. His research has been supported by prestigious organizations including the Andrew W. Mellon Foundation, the MacArthur Foundation, the National Science Foundation, and the National Institutes of Health.

Chancellor Martin's publications reveal a consistent focus on the intersection of law and political science, with particular emphasis on Supreme Court decision-making processes. His work spans methodological innovations in political methodology, empirical analyses of judicial behavior, and substantive examinations of legal doctrine. A notable trend in his scholarship is the development and application of quantitative techniques to understand judicial ideology and decision-making patterns. His most influential contributions include the Martin-Quinn scores for measuring judicial ideology and his work on the Supreme Court Database.

Chancellor Martin has secured significant research funding from major foundations and government agencies, demonstrating the impact and relevance of his scholarly work. His mentorship of graduate students has been formally recognized with the Outstanding Faculty Mentor Award. He has led major research projects including the Supreme Court Database, the EEOC Litigation Project, the development of Martin-Quinn scores, and the Supreme Court Forecasting Project.

Chancellor Martin directs several major research initiatives, most notably the Supreme Court Database project, which documents and codes every vote by U.S. Supreme Court justices from 1937 to the present. His work on the Martin-Quinn scores, developed with collaborator Kevin Quinn, has become a standard tool for measuring judicial ideology. These projects involve interdisciplinary teams of researchers, students, and collaborators working at the intersection of law, political science, and statistical methodology.
