Professor Littwin studies bankruptcy, consumer, and commercial law from an empirical perspective. Her current research includes studying the attitudes towards bankruptcy among consumers being sued by debt collectors, bankruptcy local legal culture, as well as the relationship between consumer credit and domestic violence (DV). She has published in journals such as the Texas Law Review, University of Pennsylvania Law Review, California Law Review, and American Bankruptcy Law Journal. She has recently published articles about racial disparities in bankruptcy chapter use, the Consumer Financial Protection Bureau's complaints process and supervision program as well as on how consumer bankruptcy attorneys adapted to the Bankruptcy Abuse Prevention and Consumer Protection Act. Professor Littwin has been a principal investigator for a number of empirical projects. With collaborator Adrienne Adam of Michigan State University, Professor Littwin has received funding from the National Science Foundation to study debt and domestic violence. She is working with Professor Pamela Foohey at Indiana University Maurer School of Law to study financially-distressed consumers’ knowledge of and feelings about bankruptcy and with Professor Bob Lawless at the University of Illinois to study local legal culture in consumer bankruptcy.

Professor Littwin received her undergraduate degree from Brown University and graduated from Harvard Law School in 2002. After law school, she clerked for the Honorable Rosemary Barkett of the U.S. Court of Appeals for the Eleventh Circuit and founded ROAD (Reaching Out About Depression), a community-organizing project for low-income women. Prior to her appointment at the University of Texas School of Law, she was a Climenko Fellow and Lecturer on Law at Harvard Law School. She joined the UT faculty in 2008.
