Is sexual harassment in academia an isolated problem, or s it linked to the academic work environment and culture? Research at the Faculty of Mathematic and Natural Sciences at University of Oslo supports the latter view. The results show how sexual harassment are associated with problem features of the workplace organization, envirinment and culture. This is especially clear in the cade of unwanted sexual attention, whick is closely linked to professional devaluation and other problems. Other more serious forms (unwanted physical contact, coercion, stalking, assault) are less frequent, yet clearly associated with unwanted sexual attention. The chapter presents and analyzesthe sexual harassment data in view of other recent research, and discusses why this topic is important, and how research can be improved.
