My research focuses on maternal, child and family health; the effect of the environment on child development; and domestic and sexual violence within families and communities.

My current work focuses on a cohort study that examines the role of endocrine disrupting chemicals, specifically phthalates, in child development. I am also involved in work related to vulvodynia and chronic pain.

Community Engagement

I am currently part of a working group on violence against Asian women and children, which was part of the 2015 Minnesota session (Chapter 71, Article 8, Section 58). Along with Rainbow Research, a community-based research group, I am overseeing data collection that will become part of a report and recommendations back to the Legislator and Governor in 2017. I am particularly looking at the data on prevalence estimates in Minnesota and the impact of victimization for these women and children.
