Before joining the Temple Law School faculty in 2001, 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, she was an associate attorney for Earthjustice Legal Defense Fund (formerly the Sierra Club Legal Defense Fund) in Seattle, Washington, where she represented a range of environmental, fishing, and other groups in litigation focusing on endangered species, clean water, and water conservation issues. In addition to her involvement with environmental issues, Professor Sinden was an attorney at Community Legal Services in Philadelphia, where she represented parents in civil child abuse and neglect proceedings, and advocated on behalf of welfare recipients seeking job training and education. Professor Sinden 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. Professor Sinden graduated summa cum laude from the University of Pennsylvania Law School in 1991.

Professor Sinden’s 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 and countering 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. Recent publications include Formality and Informality in Cost-Benefit Analysis, 2015 Utah L. Rev. 93, The Missing Instrument: Dirty Input Limits, 33 Harv. Envtl. L.
