Professor Joshua Galperin joined the Haub Law faculty in July 2021. Before that, Professor Galperin was on the faculty at the University of Pittsburgh School of Law since 2018, where he taught Torts, Administrative Law, Constitutional Law, and Environmental Law, Policy, and Practice. Professor Galperin was a student nominee for the Distinguished Public Service Professor award and a dean’s nominee for the Provost’s Diversity in the Curriculum award. He was also a two-time winner of the Most Valuable Professor award.

Prior to the University of Pittsburgh, Professor Galperin was the Director of the Environmental Protection Clinic, Lecturer in Law, and a Research Scholar at Yale Law School. He has been a fellow at Yale University’s Pauli Murray College from 2017 to the present. Professor Galperin was also a lecturer and the Environmental Law and Policy Program Director at the Yale School of the Environment (YSE). In addition to directing and teaching the Environmental Protection Clinic, Professor Galperin directed the dual law-environment degree program between YSE and Pace, Vermont, and Yale law schools. He was a lead collaborator in the Land Use Collaborative between YSE and Pace. Professor Galperin was also the associate director for the Yale Center for Environmental Law & Policy, where he oversaw all operations of the Center including budgeting, fundraising, research, and teaching. Professor Galperin received the award for excellence in research, teaching, and service from the YSE graduating class of 2017.

Professor Galperin’s research and teaching cover environmental law, administrative law, food and agriculture law and policy, property, constitutional law, and tort law. He has published extensively on environmental law, with particular emphasis on the role of non-governmental advocates in the creation and maintenance of environmental law, takings and just compensation, invasive species policy, and private environmental governance. His research in administrative law looks at constitutional democracy and administrative legitimacy with a focus on how governance intuitions influence political power. He has also written about food and agriculture law and policy, particularly where agriculture and food law intersect with environmental policy and administrative law doctrine. His work appears in the Georgetown Law Journal, the Columbia Journal of Environmental Law, the Stanford Environmental Law Journal, University of Pittsburgh Law Review, Cambridge University Press, University of Virginia Journal of Environmental Law, Denver Law Review, Arkansas Law Review, Vermont Law Review, Fordham Urban Law Journal, George Washington Journal of Energy and Environmental Law, and elsewhere.

Before Yale, Professor Galperin worked for the Southern Alliance for Clean Energy (SACE), where he was a policy analyst and research attorney. In that position he established and managed SACE’s coal plant retirement campaign, which was a hybrid legal, grassroots, and analytical effort to catalyze retirement of the Southeast’s oldest, dirtiest, and least efficient coal plants. Before SACE, Professor Galperin was a legislative counsel for the Vermont General Assembly, where he primarily staffed the House and Senate committees on agriculture. In that role he was involved with a number of bills that eventually became law including Vermont’s farm-to-plate investment program, dairy price stabilization, and creation of the Vermont Grape and Wine Council. Professor Galperin studied law at Vermont Law School, where he graduated magna cum laude and was a member of the Vermont Law Review’s senior editorial board. He earned a master’s degree in environmental management from the Yale School of the Environment (then the Yale School of Forestry and Environmental Studies), and a bachelor’s degree in political science with a minor in wildlife conservation from the University of Delaware.
