Ruth Ditlmann is a 4th year doctoral student. Ruth received her Diploma in Psychology from the University of Constance, Germany in 2007. Her research focuses on the role of identity in minority exclusion, particularly across cultures and subcultures. In her main line of research she investigates how national identity shapes people's reaction to immigrants in the United States and in Germany. She has also conducted research on how perceptions of multicultural policies differ depending on the ethnic background of the perceiver with Valerie Purdie-Vaughns, and on how contextual cues shape expectations towards minority and majority members. To investigate her questions of interest she adopts a multi-method approach, consisting of surveys, laboratory studies, content analysis and most recently field experimentation. Download PDF of CV.
