Research Focus

My research focus is interdisciplinary, rooted in Human Development, Psychology, Sociology, Criminology, Social Work, and Cross-Cultural Studies. My scholarship focuses on the influence of individual characteristics and contextual factors on adolescent development, toxic-stress, trauma, and resilience on ethnic/racial minorities and vulnerable youth using a cross-cultural/cross-national comparative lens. I also use a mixed-method approach to research through my background in quantitative and qualitative methods (e.g., ethnography, case studies, in-depth interviews, focus groups) and Participatory Action Research (PAR) that seeks to build an evidence-based practice for the development, extension, and improvement of prevention/intervention efforts. My research has been funded by national and international organizations including Fulbright; United States Department of State, Bureau of Educational & Cultural Affairs; The Administrative Department for Science, Technology & Innovation of Colombia-South America; Sao Paulo-Brazil Research Foundation; U.S.A Department of Education; U.S. Administration on Children, Youth, & Families among others. I am an International Adjunct Professor in the College of Applied Social Sciences at the State University of Ponta Grossa, Paraná-Brazil as well as in the Departments of Medicine, Biostatistics & Epidemiology and Psychology at CES University, Medellin-Colombia (South America). During the past 20+ years, I have been working closely with several local communities, statewide partners, national and international collaborators to support the well-being and positive development of youth. All my graduate and undergraduate students gain "hands-on" experience by participating in research activities, community outreach programs, volunteering activities, and positive development programs for youth. My research, teaching, and service have been shaped by diverse life experiences and by the people who have made those experiences possible. I have lived in different countries and cultures and thus, I seek to discover what lies beneath our multidimensional lives, to improve and advance the lives of underserved youth, and to serve the community and society at large.
