I am Acting Dean of the School of Humanities and Social Science and a Chair Professor in the Division of Social Science at the Hong Kong University of Science and Technology (HKUST).
My research focuses on demography, stratification and inequality in historical China and in comparative perspective. As a member of the Lee-Campbell group, I study official, educational, and professional elites in China from the middle of the 18th century to the present. For this, we have a family of ‘big data’ studies of specific categories of elites using datasets we have constructed ourselves from archival sources. In connection with this, I lead the study of the Qing civil service from the middle of the 18th century to the beginning of the 20th century by construction and analysis of a database of office holders we call the China Government Employee Database-Qing (CGED-Q). In addition to employing traditional quantitative approaches from the social sciences we collaborate with historians and computer scientists. I am involved in two other major projects with the Lee-Campbell Group that involve the creation and analysis of large, longitudinal, individual-level databases from archival records: a study of the social origins and careers of university students, professionals, and other elites in the first half of the twentieth century and a study of rural society in mainland China from 1949 to the mid-1960s using village-level microdata.
I continue research on kinship, inequality, and demographic behavior in historical China and in comparative perspective using large multi-generational population databases that my collaborators and I constructed, most notably the China Multigenerational Panel Datasets (CMGPD). I published on a wide variety of topics using these data, including economic, family and social influences on demographic outcomes such as birth, marriage, migration, and death, fertility limitation in historical China, and the role of kin networks in shaping social mobility. We also published related books at MIT Press and Cambridge University Press. We publicly released the CMGPD and they are are available at ICPSR.
My papers have appeared in such journals as American Journal of Sociology, American Sociological Review, Demography, Population Studies, and Demographic Research.
I was a Fellow of the Center for Advanced Study in the Behavioral Sciences at Stanford 2022-23. I was a Guggenheim Fellow in 2004 and a Changjiang Scholar (長江學者講座教授) at Central China Normal University from 2017 to 2020. From 2020 to 2023, I was a Distinguished Professor (特聘教授) in the School of History and Culture at Central China Normal University. Before I came to HKUST in 2013, I was Professor in the Department of Sociology at UCLA and an affiliate of the California Center for Population Research (CCPR) at UCLA.
I earned my MA and PhD at Penn and my BS in Engineering and Applied Science and History at Caltech.
In my spare time, I take pictures. I like to photograph cities at night and have a large collection of photos of Hong Kong at night. Lately I have been taking lots of pictures of birds. To see all of my featured collections by location and theme, please visit my photography website. You can also follow me on Instagram.
