Dr. Broll's research focuses on cyberbullying, policing, cybercrime, and victimization. For the past several years, he has studied the ways in which police officers, parents, and educators prevent and respond to cyberbullying. He is also currently researching how cyberbullying is defined laws in Canada and elsewhere, and the implications these definitions have for policing. Dr. Broll's other work has examined the role of the general public in providing security in cyberspace, and the social and emotional impacts of violence on victims. His research and writing has appeared in the Canadian Journal of Criminology and Criminal Justice, Policing & Society, Criminology and Criminal Justice, the Journal of School Violence, and other international publications.
