About Michael

Michael Sierra-Arevalo received his B.A. in sociology and psychology (high honors) from the University of Texas at Austin. He is an affiliate fellow at the Institute for Social and Policy Studies (ISPS), and a graduate student affiliate of the Center for Research on Inequalities and the Life Course (CIQLE). His dissertation research focuses on the relationships between police and the public, particularly how police perceptions of danger influence police behaviors. His research interests also include gangs, gun violence, social networks, and public policy strategies for reducing urban violence. Since 2012, Sierra-Arevalo has provided research and programmatic support to Project Longevity, a statewide gun-violence prevention program being implemented with cooperation from local police, the U.S. Attorney's Office, social service providers, and the local community.
