Jaemin Lee is an assistant professor of sociology at the Chinese University of Hong Kong. Professor Lee is a co-theme leader (socio-spatial networks) of the Computational Social Science Laboratory at CUHK. Before joining CUHK, he was a postdoctoral fellow at Northeastern University’s Network Science Institute. He holds a PhD in sociology from Duke University and a BA and MA from Yonsei University. His dissertation work has been recognized by an Outstanding Dissertation-in-Progress Award by the American Sociological Association’s Mathematical Sociology Section.
Dr. Lee uses social network models and computational text analysis to study how relational structures shape human behavior and group processes in political, economic, and organizational contexts. His current and past research agendas include:
- Experiment, simulation, and text-based approaches to political polarization
- Mapping cultural schema and meaning structures of nationalism
- Social capital and network advantages in microfinance groups
- Modeling diffusion and homophily in student and consumer populations
- Using machine learning to measure status hierarchy among cultural producers
His research has appeared in the Proceedings of the National Academy of Sciences (PNAS), Child Development, Journal of International Development, and International Journal of Sociology and Social Policy. Lee has received grant support from the Hong Kong Research Grants Council for his ongoing projects on partisan common ground in social media (Early Career Scheme) and nationalism in South Korea (General Research Fund).
Prof. Lee is an enthusiastic educator who strives to integrate quantitative research methods into students’ theoretical understanding in the age of data revolutions and artificial intelligence. He was honored with the Exemplary Teaching Award 2024 from the Faculty of Social Science at CUHK.
