Yiwan studies social epidemiology and the generational disparities in health and well-being using large-scale social survey data. Yiwan’s research focused on the baby boomers’ waning well-being and emerging socio-economic challenges millennials face. He contextualized his demographic analysis with the ongoing influences of neoliberalism and globalization. Building upon Easterlin’s relative cohort size hypothesis, Yiwan’s dissertation project seeks to understand how and why cohort size influences happiness and health over time and across generations. Yiwan is highly skilled in applied quantitative research, age-period-cohort analysis, and multilevel modeling. He has experience teaching social research methods and the sociology of health and illness.
