University Profile

Program involvement
Youth Development Graduate Programs - Academic Advisor at TTU and Instructor


Elizabeth Trejos-Castillo’s research focus is interdisciplinary, rooted in human development, cross-cultural studies, psychology, sociology, criminology, and public health. Her scholarship focuses on the importance of individual characteristics and contextual factors in the etiology of risk-taking behaviors and deviance in youth, with a particular focus on ethnic minority and at-risk populations. Her scholarship is also based on a cross-cultural comparative approach that aims to generate knowledge on minority and immigrant youth and their families and the particular characteristics of these understudies groups.

Using a mixed-method approach to research through her background in ethnography, case studies, and participatory action research approaches, she seeks to build an evidence-based practice for the development, extension, and improvement of prevention/intervention efforts. During the past nine years, she has worked closely with several local community and state-wide partners to support the well-being and positive developmental outcomes in youth.

All her graduate students and undergraduate research assistants gain hands-on experience by participating in community outreach programs, volunteering activities and positive development programs for youth. Her research, teaching, and service have been shaped by diverse life experiences and by the people who have made those experiences possible. She has lived in different countries and cultures; thus, she seeks to discover what lies beneath our multidimensional lives, to improve and advance the lives of underserved populations and to serve academia, the community, and society at large.

In 2019, Dr. Trejos-Castillo became a STEM CORE Member by the Center for Outreach, Research and Education at Texas Tech University. In 2018, she became an Executive Session on the Future of Justice Policy Member by the Columbia University/MacArthur Foundation. Dr. Trejos-Castillo received the Faculty International Scholarship Award from the Office of International Affairs at Texas Tech University in 2018. In 2018, Trejos-Castillo was selected as a Fullbright Fellow in the United States Department of State in the Bureau of Educational and Cultural Affairs.
