Initially a scholar and teacher of constitutional law and co-author of the casebook Processes of Constitutional Decisionmaking, Paul Brest now focuses on judgment and decision making, philanthropy, impact investing, and performance measurement. Professor Brest joined the Stanford Law School faculty in 1969 and served as dean from 1987 to 1999 before becoming president of the William and Flora Hewlett Foundation in 2000. He returned to Stanford in the fall of 2012, where, as an emeritus professor recalled to active duty, he is teaching courses in the Law School, Graduate School of Business, and Public Policy Program on Judgment and Decision Making, Impact Investing, Managing to Outcomes, and (together with Larry Kramer), the Ethics of Philanthropy. He is also collaborating with Professor Deborah Hensler in designing a law and public policy laboratory at the Law School and teaching a seminar, Thinking Like a Policy Analyst.
