Henry Brady is a professor of political science and public policy who serves as dean of the Goldman School of Public Policy. Formerly he directed of the Survey Research Center, which was a laboratory for developing social-science research tools. Brady has authored two books and numerous articles on political participation, political methodology, the dynamics of public opinion and other topics. In the 1990s, Brady led major evaluations of welfare reforms in California and contributed to state welfare-reform legislation. After the 2000 presidential election and the butterfly ballot snafu in Florida, he became an advocate for replacing punch-card ballots. The U.S. Ninth Circuit Court of Appeals briefly halted the 2003 California gubernatorial recall vote, in part due to Brady's research on how punch-card systems disproportionately lost votes in minority communities.
