Dr. Elizabeth Trejos-Castillo, Ph.D..

Elizabeth Trejos is an Associate Professor of Human Development & Family Studies. She is also an International Adjunct Faculty in the Department of Psychology at Universidad CES (Colombia, South America) and an Associate Editor of The Journal of Early Adolescence. Her research focuses on the importance of family / generational processes as well as individual (internalization, externalization) factors and contextual effects in youth development (early to late adolescents) and health risk-taking behaviors. Dr. Trejos’ scholarship is multidisciplinary and rooted in psychology, sociology, criminology, public health, and human development & family studies fields. Her research is driven by a cross-cultural comparative approach that seeks to generate knowledge about ethnic minorities and immigrant youth and the particular characteristics of these understudied groups. Dr. Trejos also applies a mixed-method (quantitative/qualitative) and Community-based Participatory Action Research approaches to research through her background in ethnography, case studies, and qualitative research.

During the past 7 years, Dr. Trejos has worked closely with several local and state-wide community partners for the improvement of youth prevention/intervention efforts. One of her greatest passions is community service and youth well-being and thus, she engage graduate students and undergraduate research assistants in community outreach programs, volunteering activities, and positive development programs for youth to gain "hands on" experience on their professional fields and to give back to the community. Some of her current projects include: East Lubbock Promise Neighborhood Grant, US Department of Education (CO-I, 2013-2017), Responsibility Education Program (PREP)/Youth Pregnancy Prevention Grant, Human Services of Texas / The Administration on Children, Youth, and Families (Program Evaluator, 2012-2015), Normalizing Sexual Development (NSD) Curriculum / Evidence-Based Comprehensive Sexual Education Prevention Program (CO-I, 2013-present), National Study of Psychosocial Adjustment of Early Adolescents in Colombia-South America (PI, 2012-present), Youth Adjustment in the South Plains Region, (PI, 2011-present), among others.
