Dr Ruixin CHI

Research Fellow

Ruixin is a nutrition and cardiometabolic epidemiologist and a Research Fellow in Work Package 3 of the Health-Driven Design for Cities (HD4) study. She received her bachelor’s degree from Peking Union Medical College, completed her clinical internship at Peking Union Medical College Hospital, and received the Beijing Outstanding Undergraduate Thesis Award. She was also selected as a fully funded Visiting Scholar at the University of North Carolina and completed her PhD at Peking University as a recipient of the President’s Scholarship.

Ruixin’s research sits at the intersection of nutrition, epidemiology, and cardiometabolic health. She has rich experience in population-based research and has worked closely with organisations such as UNICEF and the Chinese Nutrition Society, centres for disease control and prevention, and hospitals. These experiences have shaped her interest in understanding how everyday environments, behaviours, and broader social contexts influence long-term health.

Within HD4, Ruixin primarily leads research using SG100K to examine how dietary factors are associated with cardiometabolic health. Beyond this core scientific role, she contributes to the wider development and implementation of the HD4 research infrastructure, including the construction and harmonisation of built-environment exposure data dictionaries, postcode-based geocoding, API-enabled linkage to official planning-area information, and the integration of spatial exposure variables into epidemiological analysis datasets. She also contributes more broadly to studies investigating how built-environment exposures may shape dietary behaviours and health outcomes from an epidemiological perspective.

Ruixin is delighted to be part of the HD4 team and looks forward to working with colleagues across disciplines to produce thoughtful, meaningful, and exciting research for healthier cities and healthier lives.
