As a sociologist and social demographer, Yiang studies the dynamics of social inequality—particularly health disparities—and their determinants in the social contexts—family structures and neighborhoods. His research focuses on uncovering early-life precursors and underlying mechanisms that shape, perpetuate, and reproduce health differentials and social disadvantages from one generation to the next using temporal, developmental, and place-based perspectives. Additionally, he adopts a comparative perspective to study how population processes across countries are linked to morbidity and mortality patterns.
He applies statistical, demographic, and computational techniques to study health disparities linked to contemporary and historical population processes, with a focus on causal inference, data linkages, and large-scale analytics. He has won the competitive ASA Travel Awards alongside funding support from Coordinating Centers on Demography and Economics of Aging.
His research work has been published in Social Forces, Lancet Regional Health, and Journal of Computational Social Science, among other peer-reviewed journals.
