Food justice activists have worked to increase access to healthy food in low-income communities of color across the United States. Yet despite their best intentions, they often perpetuate food access inequalities and racial stereotypes. Hanna Garth shows how the movement has been affected by misconceptions and assumptions about residents, as well as by unclear definitions of justice and what it means to be healthy. Focusing on broad structures and microlevel processes, Garth reveals how power dynamics shape social justice movements in particular ways.Drawing on twelve years of ethnographic research, Garth examines what motivates people from more affluent, majority-white areas of the city to intervene in South Central Los Angeles. She argues that the concepts of "food justice" and "healthy food" operate as racially coded language, reinforcing the idea that health problems in low-income Black and Brown communities can be solved through individual behavior rather than structural change. Food Justice Undone: Lessons for Building a Better Movement (U California Press, 2026) explores the stakes of social justice and the possibility of multiracial coalitions working toward a better future.

Hanna Garth is Assistant Professor of Anthropology at Princeton University, author of Food in Cuba: The Pursuit of a Decent Meal, and coeditor of Black Food Matters: Racial Justice in the Wake of Food Justice.

Untangling the Political Roots of Immigration and Inequality in the United States (Routledge, 2026) examines the causes, consequences, and politics of mass migration and growing inequality by investigating the case of the United States – the quintessential immigrant nation. While scholars, policy makers, and advocates have put forth a variety of explanations, many misdiagnose the causes and put forward remedies that treat symptoms. This book looks to the root causes of mass migration and intensifying inequality, arguing that they are two sides of the same coin resulting from rapacious forms of capitalist accumulation and imperialist interventionism. Developing a broadly left analytic framework grounded in elements of Marxist theory and political science, two periods are examined – 1870–1925 and 1970–2025 – when the proportion of immigrants in the US peaked at 15% of the total population, the US experienced steep inequality and political polarization, immigration and inequality became contentious political issues that generated sharp conflict, and immigrants and workers organized mass movements that advanced radical politics and transformative change. This book contains a wealth of information and elevates valuable lessons for scholars, policy makers, and organizers interested in understanding these trends and forging equitable and just solutions today.

San Francisco's Chinatown is the oldest Chinatown in North America and one of the largest Chinese enclaves outside Asia. Spanning 30 city blocks and home to tens of thousands of monolingual Chinese residents, its endurance is remarkable—especially given how close it came to erasure.

In Chinatown: San Francisco's 1906 Earthquake and the Paradox of American Immigration Policy (JHU Press, 2026), Dr. Dafeng Xu uncovers the contested history of this vibrant community, focusing on the transformative period surrounding the 1906 earthquake and fire that destroyed 80 percent of the city, including Chinatown. White San Franciscans saw the disaster as an opportunity to permanently displace the neighborhood. Instead, Chinatown was rebuilt—but not without conflict or consequence. Using detailed census data and other historical documents, Dr. Xu examines how this rebuilt Chinatown differed socially and physically from its earlier form—and the many ways it stayed the same. He explores whether the earthquake shifted patterns of segregation, if and how Chinese immigrants navigated pressure to assimilate—including adopting English, changing their names, and leaving ethnic neighborhoods—and whether they gained economic ground in the city's new landscape.

Dr. Xu's study reveals a striking contradiction: while Chinese Americans were often criticized for not assimilating, systemic barriers made that very process nearly impossible. The post-disaster Chinatown became a symbol of cultural resilience, shaped by both community agency and persistent exclusion. Rich in insight and original research, Chinatown offers a powerful look at how disaster, racism, and resistance shaped one of America's most storied immigrant neighborhoods.

This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

Disproving the popular narrative that shootings are the calculated acts of malicious or desperate people, Ludwig shows how most shootings actually grow out of a more fleeting source: interpersonal conflict, especially arguments. By examining why some arguments turn tragic while others don't, Ludwig shows gun violence to be more circumstantial—and more solvable—than our traditional approaches lead us to believe.Drawing on decades of research and Ludwig’s immersive fieldwork in Chicago, including “countless hours spent in schools, parks, playgrounds, housing developments, courtrooms, jails, police stations, police cars, and lots and lots of McDonald's,” Unforgiving Places: The Unexpected Origins of American Gun Violence (University of Chicago Press, 2025) is a breakthrough work at the cutting edge of behavioral economics. As Ludwig shows, progress on gun violence doesn’t require America to solve every other social problem first; it only requires that we find ways to intervene in the places and the ten-minute windows where human behaviors predictably go haywire.

Jens Ludwig is the Edwin A. and Betty L. Bergman Distinguished Service Professor at the University of Chicago Harris School of Public Policy.
