Dr. Marc Jambon

Post-Doctoral Fellow


I received my Ph.D. in developmental psychology from the University of Rochester in 2016 under the advisement of Dr. Judith Smetana. I joined Dr. Malti’s laboratory as a post-doctoral fellow in September, 2017.


My research focuses on moral development in childhood and adolescence, with a particular interest in understanding why people engage in acts of harm, injustice, and unfairness towards others. This central question has guided my interest in the development of individual differences in preschoolers’ reasoning about moral and social norms, the connections between moral judgments, emotions, and behavior, and how different social experiences (e.g., with peers, family members, and the broader society) contribute to children’s and adolescents’ moral beliefs and values. I am also interested in developing new and improved methods to assess moral evaluations in early childhood. My ultimate goal is to help build a more integrated understanding of the crucial role that moral functioning plays in children’s broader social, emotional, and behavioral development.
