Chengdu Positive Child Development (CPCD) Survey
Project Description

I directed the 5th wave of the survey, including coordination with participating schools and logistical planning and managed field surveys, data entry using Epidata, and ensured accuracy in preliminary data processing.

I independently conducted data matching, screening, cleaning, and missing value imputation for Waves 1-4, then developed a longitudinal machine learning model to predict adolescent NSSI, published in Journal of Affective Disorders, 2025.

Chinese General Social Survey (CGSS)
Project Description

I co-led the 2023 Sichuan Province survey team, with responsibilities including project planning and coordination, field household interviews, and software management.

Chronic Disease and Health Literacy Survey

I led a chronic disease and health literacy survey across 7 Sichuan Province cities, organizing field data collection and interviews, analyzing and visualizing results, and preparing the research report for government departments.
