Ron Avi Astor holds joint appointments in the USC School of Social Work and USC Rossier School of Education. His work examines the role of the physical, social-organizational and cultural contexts in schools related to different kinds of school violence (e.g., sexual harassment, bullying, school fights, emotional abuse, weapon use, teacher/child violence). Astor’s studies have included tens of thousands of schools and millions of students, teachers, parents and administrators. Over the past 10 years, findings from these studies have been published in more than 150 scholarly manuscripts.
