Profile Headshot


Professor Capellan specializes in statistics and spatial analysis. Substantively, his research interests are broad.  He has conducted and published research on state-sponsored repression, segregation, mass public shootings, lone-wolf terrorism, policing bias, and criminological and sociological theories. Currently, he is devoting most of my attention to the study of mass public shootings. 

Dr. Joel Capellan is an Assistant Professor of Law and Justice Studies at Rowan University. He received his Ph.D. in Criminal Justice from the CUNY Graduate Center in 2016. Prior to his doctoral studies, Dr. Capellan earned an M.A. in Social Science Research from the University of Chicago and a B.A. from Buffalo State College.
