Interests: Cross-cultural approaches to adolescent development in the context of accelerated change in digital technologies


I lead the interACTlab (International Adolescent Connection and Technology Laboratory). Our research focuses on how the social and affective developmental tasks of adolescence have been transformed by the digital era—particularly in understudied populations in international settings.

We collaborate with schools in Latin America to advance knowledge on adolescent development and technology use, and also apply developmental science to design school-based interventions to promote digital citizenship and healthy digital habits. This research-practitioner partnership allows us to better expand our understanding of, and respond to the needs of, young people in these key formational years in an increasingly digitalized world.

My long-term goal is to leverage my background in developmental psychology, cognitive neuroscience, and cross-cultural contexts to advance our understanding of how adolescent development is shaped by the risks and opportunities afforded by digital technologies.
