Biography

David S. Cohen’s teaches courses on constitutional law, sex discrimination, and reproductive rights and justice. His scholarship explores the intersection of constitutional law and gender with a particular focus on how the law impacts abortion provision. He also researches sex segregation, masculinity, and voting anomalies at the Supreme Court.

In the wake of the reversal of Roe v. Wade, Professor Cohen has been one of the leading national experts on abortion. Along with his coauthors Greer Donley (Pitt) and Rachel Rebouché (Texas), he has written several oft-cited law review articles about the aftermath. In particular, their 2023 Columbia Law Review article was cited by the dissenting opinion in Dobbs and has been the inspiration for at least 22 state laws and executive orders passed to protect abortion rights in the face of the Supreme Court’s reversal. Their Stanford Law Review predicted and analyzed the current battles over medication abortion that have consumed the post-Dobbs landscape. The trio have also published four op-eds in the New York Times as well as many in other outlets, including Slate, the Atlantic, and Politico.

Professor Cohen has also coauthored three books about abortion provision and the law. His most recent, After Dobbs: How the Supreme Court Ended Roe But Not Abortion (with Carole Joffe (UCSF)), was published by Beacon Press in 2025. It was reviewed in the New York Review of Books and was the subject of a symposium published by the Fordham Law Review Online. Professor Cohen’s second co-authored book was published in 2020, Obstacle Course: The Everyday Struggle to Get an Abortion in America. Published by California University Press and also written with Carole Joffe, Obstacle Course explores the practical realities of accessing abortion amidst the tangled web of restrictions across the country. His first book, Living in the Crosshairs: The Untold Stories of Anti-Abortion Terrorism, was published in 2015 by Oxford University Press and co-authored with Kline Law 2012 grad Krysten Connon. The book examines how abortion providers are individually targeted by anti-abortion extremists and how law can better respond to this type of harassment.

Professor Cohen has also published articles in the Stanford Law Review Online, Michigan Law Review, Harvard Journal of Law and Gender, Columbia Journal of Gender and Law, University of Pennsylvania Law Review Online, George Washington Law Review, Indiana Law Journal, Boston University Law Review, Seton Hall Law Review, and the South Carolina Law Review. He has a chapter in Feminist Judgments: Rewritten Opinions of the United States Supreme Court (Cambridge University Press 2016) that re-writes the 1981 Supreme Court opinion that approved the all-male military draft and a chapter in Feminist Judgments: Reproductive Justice Rewritten (Cambridge University Press 2020) that re-writes the 2016 Supreme Court opinion that struck down two Texas abortion restrictions. He is also a frequent source in major media outlets about current developments in abortion and the law.

After clerking for Justice Alan B. Handler of the New Jersey Supreme Court and Judge Warren J. Ferguson of the U.S. Court of Appeals for the Ninth Circuit, Professor Cohen worked as a fellow and staff attorney for the Women’s Law Project in Philadelphia. There, he handled a range of cases involving reproductive rights, sex discrimination under Title IX, health insurance coverage of contraceptives, health care for women prisoners and family rights for gay and lesbian couples. Professor Cohen worked on several U.S. Supreme Court cases, including representing the plaintiffs in Ferguson v. City of Charleston.
