Hi, and welcome! I am Sinn Won Han, an Assistant Professor of Sociology at Yonsei University in Seoul. Before joining Yonsei, I taught at the University of Hong Kong and completed a postdoctoral fellowship at Cornell University's Jeb E. Brooks School of Public Policy. I earned my Ph.D. in sociology from Harvard University. 

I am a social demographer studying low fertility and family change in postindustrial societies, with a particular focus on South Korea, East Asia, and cross-national comparison. My research examines how structural conditions—such as labor-market transformation, economic precarity and uncertainty, and institutional constraints—interact with cultural expectations surrounding family formation to shape individuals' decisions about long-term commitments. Research from this line of inquiry has been published in Demography, Population and Development Review, European Sociological Review, and Chinese Sociological Review, among others. 

My email address is sinnwon@yonsei.ac.kr, and I welcome any conversation regarding research.
