Lisa Hahn is a Ph.D. Candidate at the Faculty of Law, Humboldt University Berlin (Germany). Her dissertation explores conditions of social change through strategic litigation in Germany. In this project she develops the idea of ‘litigation collectives’ as key factor for the success of strategic claims. During her research stay at the Center for the Study of Law & Society, Lisa will be working on a comparative chapter that juxtaposes the expansion of strategic litigation as a particular mode of legal mobilization in the US, Germany and on the transnational level. Besides her primary focus on courts, litigation and social movements, she is further interested in feminist legal studies, migration studies and socio-legal research methods. Lisa is a lawyer by training but was familiarized with research methods in social sciences through her work in an ethnographic research project on migration and German administrative law between 2016 and 2017. In 2018, she co-founded the graduate network Socio-Legal Lab. Through workshops, summer schools, film screenings and informal get-togethers, the Socio-Legal Lab provides a space to discuss the challenges of interdisciplinary research on law and society. Moreover, she is a member of the project group of the Integrated Research Institute “Law & Society” at Humboldt University Berlin. (1/6/20 – 4/30/20)

Mel Greenlee received her PhD in Linguistics and her J.D. from the University of California-Berkeley. Subsequently, she conducted research on language acquisition, bilingualism and other sociolinguistic topics at CUNY’s Centro de Estudios Puertorriqueños, UCLA and Stanford, before returning to academia as a law student, where she focused on criminal defense and immigration law. Later, as a senior staff attorney at the California Appellate Project (CAP) in San Francisco, her defense work of over two decades centered on legal assistance to California capital appeals and in habeas corpus matters, aiding the ever-growing number of prisoners sentenced to death in challenging their convictions and sentences at the post-conviction stage. For many years, she has also conducted trainings and workshops on the role of language in capital trials and presented linguistic analysis of courtroom language to U.S. and international fora, addressing, for example, interpreter error, implications of prosecutors’ arguments, defense objections, and the role of language in determining a defendant’s competence to stand trial or for self-representation. Her work has appeared in such diverse journals as Language & Law/Linguagem e DireitoApplied Psycholinguistics, and the Journal of Pragmatics. Currently, having retired from her CAP attorney role, she continues her research and publication on sociolinguistic aspects of criminal cases, particularly as these affect capital proceedings.  (1/6/20 – 5/31/20)

Dana Hayward is a doctoral candidate in the Department of Sociology at Yale University. Her research explores the culture-shifting potential of the law – in other words, the power of the law to alter social norms and values. However, it can be difficult to study the cultural impact of legislation empirically, as laws both shape and are shaped by their cultural contexts. In her work, Dana suggests that a comparative analysis of close votes offers a promising solution to this dilemma. Drawing on insights from quasi-experimental research design, she argues that legislative decisions that pass or fail by narrow margins allow for comparisons in which levels of cultural support for law reform are held constant. While in residence at the Center, Dana will be working on her dissertation, which asks: How does legislative change affect the framing of moral issues? She conducts a qualitative comparative-historical analysis of four narrowly approved or defeated citizens’ initiatives that appeared on the ballot in the Western United States between 1990 and 1998. In each case, she compares how the issue was framed before, during, and after the approval or defeat of the measure, focusing particularly on media, political, and social movement discourses. She looks specifically at legislation in the issue areas of physician-assisted death and parental notification of abortion, as these issues raise similar sociological and ethical questions about bodily autonomy, informed consent, and the power of the state to regulate life and death. Dana holds an M.A. in Sociology from Yale, as well as an M.A. in Political Science and a B.Soc.Sc. (summa cum laude) in International Development and Globalization from the University of Ottawa.

is an Assistant Professor of Law at the University of Wisconsin Law School and a Faculty Affiliate with the Sociology Department at the University of Wisconsin. Gwyn’s research examines how the interaction between law and social movements affects patterns of inequality and social change.

She is currently working on a book, Litigation and the Shaping of the LGBT Movement (1985-2015), which highlights a series of mechanisms that have enabled litigation to dominate the agendas of LGBT and queer activists working outside the courtroom.
