My research focus is interdisciplinary, rooted in Human Development, Cross-Cultural Studies, Psychology, Sociology, Criminology, and Public Health. My 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. My scholarship is also based on a cross-cultural/cross-national comparative approach that aims to generate knowledge on minority and immigrant youth and the characteristics of these understudied groups. I 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) approaches that seeks to build evidence-based practice for the development, extension, and improvement of prevention/intervention efforts. During the past 20+ years, I have worked closely with several local community and state-wide partners and international collaborators to support the well-being and positive developmental outcomes in 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 populations, and to serve academia, the community, and society at large.
