Professor Ron Avi Astor is the Richard M. and Ann L. Thor Professor of Urban Social Development at the University of Southern California (USC), where he holds joint appointments in the School of Social Work and the Rossier School of Education. His research examines the ecological influences of the family, community, school and culture on different forms of school violence. Professor Astor has developed a school mapping and local monitoring procedure to minimize school violence, which is now used in all Israeli schools and across the globe, including in California, Chile, and France. One of his five books, School Violence in Context: Culture, Neighborhood, Family, School, and Gender (2005, Oxford University Press), co-authored by his close colleague Professor Rami Benbenishty from Bar-Ilan University, was awarded several prizes. Professor Astor twice received a distinguished Research Award in Human Development and Counseling, and in 2012 he was named an American Educational Research Association fellow. In 2010, he received an honorary doctorate from Hebrew Union College.
