James Lubben is Professor Emeritus at UCLA where he taught for 20 years and was Associate Dean and Department Chair. He is also Professor Emeritus at Boston College where he was the Louise McMahon Ahearn Endowed Professor in Social Work for 15 years. During his 35 years in the academy, Dr. Lubben mentored over 200 doctoral students and junior faculty. He served on over 50 doctoral dissertation committees and secured dissertation research funding for over 150 doctoral students. He has published over 125 peer reviewed articles and chapters and edited 7 books. He has been a principal investigator or collaborator on over $35 million (direct costs) of research and training grants.

The primary aim of his research examines social isolation as a behavioral health risk among older populations. To carry out this research, he developed the Lubben Social Network Scale (LSNS), an abbreviated measure designed for both research and clinical use among older populations. The LSNS has been translated into many languages and employed in studies throughout the world. Scores on the LSNS have been associated with a wide array of health indicators including mortality, morbidity, psychological distress and loneliness, cognitive impairment, and health care use.

Dr. Lubben served many years as a consultant to the World Health Organization regarding health and welfare systems development for aging societies.  He also served as a Fulbright Senior Specialist to Chile. Dr. Lubben served four terms (12 years) on the congressionally mandated Gerontology and Geriatrics Advisory Committee for the Secretary of the U.S. Department of Veterans Affairs. He was elected to three different national boards for social work education: Society for Social Work and Research, Council on Social Work Education, and the Group to Advance Doctoral Education. He also served two terms (6 years) on the Executive Committee for the Grand Challenges in Social Work Initiative sponsored by the American Academy of Social Work and Social Welfare. Dr. Lubben is a Fellow in the American Academy of Social Work and Social Welfare and also a Fellow of the Gerontological Society of America.

Liz Koslov is an Assistant Professor in the Department of Urban Planning and Institute of the Environment and Sustainability at UCLA, where she studies the social dimensions of climate change, questions of environmental and climate justice, and how cities are adapting to effects such as extreme weather and sea-level rise.

Recent publications include pieces on sociology and the climate crisis, flood maps, and the possibilities for collective climate adaptation amidst denial and public silence. Her current book project, Retreat: Moving to Higher Ground in a Climate-Changed City, offers an ethnographic account of “managed retreat” from the coast in New York City after Hurricane Sandy. Koslov’s research on this topic has been cited in outlets such as Scientific American,The New Yorker, and WWNO New Orleans Public Radio.

Prior to joining UCLA, Koslov was a Mellon Postdoctoral Fellow in the Humanities at MIT.

Amada Armenta

/in , , , , , , /by

Amada Armenta’s research examines the connections between the immigration enforcement system and the criminal justice system, and the implications of this connection for immigrants, bureaucracies, and cities.

Her award-winning book, “Protect Serve and Deport: The Rise of Policing as Immigration Enforcement” (University of California Press, 2017), analyzes the role of local law enforcement agencies in immigration enforcement in Nashville, Tennessee. Currently, she is working on her second book project, an examination of the legal attitudes of unauthorized Mexican immigrants in Philadelphia.

Dr. Armenta’s research has been published in journals of sociology, law and society, and policy. She has received research funding from the American Sociological Association, the National Science Foundation, the American Society of Criminology, and the Andrew W. Mellon Foundation.

Prior to joining Luskin as a faculty member, she was an assistant professor of sociology at the University of Pennsylvania.

Amy Ritterbusch

/in , , , , , , /by

Dr. Amy E. Ritterbusch is an Associate Professor of Social Welfare at the UCLA Luskin School of Public Affairs. Her work illuminates both the theory and practice of participatory action research (PAR), invoking the Latin American origins of this mode of inquiry, and focuses on multiple forms of state violence perpetrated against what she and activist co-authors refer to as ‘street-connected’ communities, including children and youth who depend on the streets for survival in the absence of other caring structures. Dr. Ritterbusch leads PAR collectives in Colombia and Uganda that work in solidarity with street-connected-communities against police violence and forced displacement.

The urgency of action, from the streets toward policy, is a key focus of Dr. Ritterbusch’s scholarship, and her work offers methodological and theoretical insights on how to do PAR with historically marginalized communities in ways that repel extractive, unilateral, and colonial modes of traditional scientific inquiry.  Throughout her research and teaching career, she has explored different forms of radical accompaniment of social leaders on the frontlines in the global South and continues to imagine new pathways forward toward a Fals Bordian ciencia popular involving the collective work of movements and academics in protective spaces that grow in distance from both the non-profit and academic industrial complex.

Dr. Ritterbusch’s scholarship involves public intellectual work in the global South including human rights shadow reports, street-level organizing and collective writing that seeks to influence policy outcomes for social justice. Her research has been funded by the Open Society Foundations, the National Science Foundation, the Fulbright U.S. Program and other networks promoting global social justice.

Emily Weisburst

/in , , , , , , /by

I am an Assistant Professor of Public Policy at the Luskin School of Public Affairs at the University of California, Los Angeles. My research focuses on topics in labor economics and public finance, including criminal justice and education.

I recently earned my Ph.D. in Economics from the University of Texas at Austin. While in graduate school, I worked as a Staff Economist at the Council of Economic Advisers in the Executive Office of the President and as a research associate for the RAND Corporation on joint projects with the Texas Higher Education Coordinating Board. I have also received the NAED Spencer Dissertation Fellowship to support my research on the impact of funding for police in public schools on student disciplinary outcomes and educational attainment in Texas.

My research interests include understanding factors that impact police decision-making and public trust in police. I am also interested in how interactions with the criminal justice system affect individuals, families and communities. A recent paper examines how much police discretion matters to law enforcement outcomes, after accounting for offense context. In this project, I find that the likelihood that an incident results in an arrest critically depends on the officer that shows up to respond to an offense reported through a police call for service.
