Jim Greiner is the William H. Bloomberg Professor of Law at Harvard Law School, where he teaches courses on civil procedure, expert witnesses, and voting regulation. Before coming to HLS in 2007, Jim completed his Ph.D. in statistics at Harvard University. Prior to this, Jim practiced law for six years, three for the Department of Justice (Federal Programs Branch), and three for Jenner & Block. He tried to focus his practice on employment discrimination, voting rights, and the Decennial Census, but alas, he also had to learn how airplanes get on and off aircraft carriers (in the A-12 litigation, originally filed over 20 years ago and still going), as well as how to deal with structural injunctions in long-running housing desegregation cases. Currently, Jim's research focuses on randomized field experiments in the legal setting, particularly in access to justice and adjudicatory administration. He has published papers on three such experiments and has another nine either in the field or in planning. His work has been published in a variety of venues including the Harvard Law Review, the Yale Law Journal, the Journal of the Royal Statistical Society (Series B), the Annals of Applied Statistics, and Jurimetrics.
