Professor of Law
Faculty Director, UCLA Sustainable Technology and Policy Program
Frank G. Wells Endowed Chair in Environmental Law

  • B.A. Villanova University, 1982
  • J.D. University of Pennsylvania, 1986
  • UCLA Faculty Since 1998

Timothy Malloy teaches Environmental Aspects of Business Transactions, Regulatory Lawyering, Regulation of the Business Firm, Environmental Policy and Politics, and Contracts. After receiving his law degree, Professor Malloy clerked for Judge Donald W. VanArtsdalen of the U.S. District Court for the Eastern District of Pennsylvania. He joined the UCLA faculty in 1998, after spending a combined 11 years in practice at private firms and at the United States Environmental Protection Agency (EPA), Region III. Professor Malloy's research interests focus on environmental, chemical and nanotechnology policy, regulatory policy, and organizational theory and decision analysis, with particular emphasis on the relationship between regulatory design and implementation and the structure of business organizations. He is the faculty director of the Environmental Science and Engineering doctoral program in the Institute of the Environment and Sustainability. He serves on the EPA’s Board of Scientific Counselors and on the State of California’s Green Ribbon Science Panel.
