Phillip L. Hammack is Professor of Psychology and Director of the Sexual and Gender Diversity Laboratory at the University of California, Santa Cruz. He received his PhD in Human Development from the University of Chicago in 2006, with a concentration in Cultural Psychology. He uses qualitative and mixed methods to study the experience and development of individuals diverse in their expressions of sexuality, gender, and/or intimacy. Hammack has also been a leader in the field of narrative psychology, contributing both conceptual and methodological innovations. He is past president of the Society for Qualitative Inquiry in Psychology and co-editor of Psychology & Sexuality.

Adriana Manago is an associate professor of psychology at UC Santa Cruz. She received her PhD in developmental psychology from UCLA in 2011, with an interdisciplinary emphasis from the Center for Culture, Brain, and Development. Her research aims to shed light on the implications of evolving digital tools for how diverse young people construct and navigate social connection and identity during adolescence and the transition to adulthood. She uses mixed methods, including youth-led social media tours and natural experiments, with adolescents primarily in the U.S. and in a Maya community in Mexico to better understand the role of digital technologies in social and identity development, cultural transmission and change. Adriana’s work contributes to multiple fields at the intersections of adolescent development, culture, and communication, and has been published in journals such as Developmental Psychology, Cross-Cultural Psychology, Computers and Human Behavior, and Sex Roles.
