P. RIchard Hahn develops novel statistical methods for analyzing data arising from the social sciences: psychology, economics, education, and business. His current focus revolves around causal inference using regression tree models, as well as foundational issues in Bayesian statistics.
Hahn joined ASU after six years at the University of Chicago Booth School of Business. His doctorate is from the Duke University Department of Statistical Science. Before that he earned a master's degree in mathematics from New Mexico Institute of Mining and Technology and a bachelor's degree in philosophy of science from Columbia University.
Originally from Lincoln, Nebraska, Hahn enjoys his new home in the southwest. When he isn't analyzing data or developing statistical software he likes to hike, bike and take photographs.
