Professor Sinden joined the faculty of Temple University Beasley School of Law in 2001, bringing a decade of experience in public interest law. Her recent academic writings have criticized the misuse of economic theory in environmental law, arguing against the use of cost-benefit analysis in environmental standard setting. In addition she has countered claims that private property rights can solve environmental problems in the absence of government regulation. She has also written about the application of classical human rights norms to environmental conflicts. Her articles have appeared in a number of books and academic journals, including the Iowa Law Review, University of Colorado Law Review, and Harvard Environmental Law Review. She is on the Board of Directors of the Center for Progressive Reform.

Before joining the law school faculty, Professor Sinden served as senior counsel for Citizens for Pennsylvania’s Future, handling litigation on behalf of PennFuture and other citizens’ and environmental groups. Prior to this position, Sinden was an associate attorney for the Earthjustice Legal Defense Fund in Seattle, Washington, where she litigated federal environmental cases focusing on natural resource issues. She also served twice as a law clerk, first for Judge John F. Gerry of the U.S. District Court for the District of New Jersey, and later for Judge Dolores K. Sloviter of the U.S. Circuit Court of Appeals for the Third Circuit.
