Professor Mary Crossley's scholarship has focused on issues of inequality in the financing and delivery of health care, encompassing topics ranging from how health insurance coverage effectively discriminates against unhealthy people to how hospitals’ community need health assessments can be tools for addressing racial health disparities. She has published broadly, in journals including Columbia Law Review, Notre Dame Law Review, and Michigan Journal of Race and Law. Crossley's scholarly interests are reflected in a seminar that she has developed on Health Justice, and she has also taught courses in Health Law and Policy, Bioethics & Law, Health Care Compliance, Family Law, and Torts.
Crossley was appointed Dean and Professor of Law at the University of Pittsburgh School of Law in 2005 and served as Dean from 2005-2012, focusing her leadership on initiatives relating to curricular reform, innovation programming, and promoting diversity. In 2013 she was selected as a Robert Wood Johnson Foundation Public Health Law Scholar in Residence, and in 2014-15 she served as a Faculty Mentor for the Robert Wood Johnson Foundation Future of Public Health Law Education Faculty Fellowship Program. She was elected to the ALI in 2016.
Immediately prior to coming to Pitt Law in 2005, Crossley was the Florida Bar Health Law Section Professor of Law at Florida State University and before that she was on the faculty at the University of California, Hastings College of the Law, including two years of service as Associate Academic Dean. Before beginning to teach, she practiced corporate and health care law in San Francisco and New Haven, and clerked for Judge Harry Wellford on the Sixth Circuit Court of Appeals.
