Joshua Bloom is Director of Programs and Development at the Institute for Research on Labor and Employment, and a doctoral candidate in the Sociology Department at the University of California, Los Angeles. He studies social movements, labor, methodology, and race. He is co-editor with Ruth Milkman and Victor Narro of Working for Justice: the LA Model of Organizing and Advocacy (Cornell University Press, 2010). His work-in-progress, Pathways of Insurgency: Black Liberation Struggle and the Second Reconstruction in the United States, 1945-1975, compares three waves of postwar Black Liberation Struggle and argues that insurgent mobilization proliferates when movement actors develop practices which, given historically particular political cleavages, destabilize target institutions while drawing broad allied support. Before becoming an academic, Joshua worked for eight years as an organizer.
