Yi Yihang Sun


I’m excited to start this new journey with SIG! I’m passionate about developing interventions to improve the well-being of marginalized children and youth. I look forward to the learning opportunities at SIG.


Yihang (Yi) Sun is a doctoral student at the Columbia University School of Social Work. Yi’s current research focuses on understanding childhood adversity and trauma in cross-cultural contexts and examining factors that contribute to resilience among ethnic minority children and youth in rural China. She is particularly interested in building trauma-informed interventions for schools and organizations.

Currently, Yi is working with Dr. Alissa Davis on various projects, including the SPARK (reducing HIV stigma to increase HIV testing among adolescents & young adults in Kazakhstan using a crowdsourcing approach), the ARC (adolescent responses to COVID-19), and the BV study (women’s experiences with bacterial vaginosis).

Prior to coming to Columbia, Yi worked as a research associate at the University of Michigan to develop an online CBT program for emotional well-being and social connection. Yi has years of multi-cultural practice experience with racial and ethnic minority populations in the US and China. She previously served as the founder and director of “Meng He Chu (Where Dream Lies)”, a community organization dedicated to improving the well-being of ethnic minority children and families affected by extreme poverty in rural China.

Yi earned her Master of Social Work degree from the University of Michigan School of Social Work.
