My research focuses on developing and evaluating interventions to improve early childhood development (ECD), with particular attention to the interplay among caregiver mental health, parenting practices, and child developmental outcomes. I conduct randomized controlled trials (RCT) and use both quantitative and qualitative methods to examine whether interventions work, how they work, and how effective interventions can be delivered at scale. Most of my research has been conducted in underserved communities in China, where I also study how evidence-based interventions can be integrated into existing government infrastructure. My long-term goal is to identify effective and scalable approaches to strengthening caregiving environments so that young children in underserved settings can thrive.
