Yoonsun Choi studies minority youth development; effects of race, ethnicity, and culture in youth development; children of immigrants; Asian American youth; and prevention of youth problem behaviors. Prof. Choi teaches courses in research methods and immigrant adolescents for masters' students and foundation statistics for doctoral students. Her background includes several years of clinical social work practice experiences in a variety of agencies with diverse populations. She worked with ethnic minority youth with severe emotional and/or behavioral problems and their families, children in foster care, mentally ill immigrant adults, and HIV+ immigrants with limited English proficiency.
Her research seeks to understand the familial and environmental processes that influence and impact ethnic minority children and their development and serves to inform the development of age- and culturally appropriate preventive interventions. She has conducted a series of interrelated research projects to identify the multiple developmental trajectories of Asian American youth and the factors that predominate in the determination of these outcomes.
