To change the world, my friend Sancho, is not madness nor utopia. It's JUSTICE!
~Miguel de Cervantes, 'Don Quixote'

Cure sometimes, treat often, comfort always.

Welcome to Dr. Trejos' Positive Youth Development (PYD) Lab!

Our research focuses on the importance of individual characteristics and contextual influences on youth developmental outcomes, risk-taking behaviors, well-being and resiliency. Our lab seeks to generate knowledge on youth in general with a focus on minority, immigrant, and international understudied youth populations. Our work is informed by multidisciplinary theories and based on cross-cultural/cross-national comparative mixed-methods (qualitative/quantitative), and Participatory Action Research (PAR).
