Anna Stetsenko, who earned her Ph.D. from Moscow State University, is widely recognized for her research in developmental psychology. Her work cuts across multicultural and multitheoretical lines, and she is fluent in English, Russian, German, and French. She is today acknowledged as an outstanding representative of post-Vygotskian activity theory, which has become one of the most important developmental psychology theories in the United States. Her articles on activity theory, including those on the topics of the self, learning and development, and the history of psychology, expanded into new theoretical and empirical areas, and her extensive empirical research into children's beliefs and school performance is now recognized as some of the most important of its kind. Her articles appear in major journals in developmental and social psychology. She is on editorial boards of international journals and is a member of various expert committees in psychology. Before coming to The Graduate Center, Professor Stetsenko taught at Moscow State University and the University of Berne, Switzerland, and was a postdoctoral scientist at the Max Planck Institute for Human Development and Education.
