Peter F. Titzmann

Peter F. Titzmann is a psychologist at the Institute of Psychology, Leibniz University Hannover whose research centers on the acculturation and development of immigrant and ethnic minority youth. Titzmann has published extensively on topics including acculturative change over time, ethnic discrimination, interethnic friendship formation, language brokering, and the adaptation of adolescents navigating between heritage and host cultures. Much of this work draws on longitudinal and diary methods to examine how developmental and acculturative processes unfold across contexts such as school, family, and peer networks. Titzmann has also contributed to broader conversations in developmental science about the inclusion of majority world perspectives in psychological research.
