I am a Professor in the Division of Social Science at the Hong Kong University of Science and Technology.  I am also Associate Dean in the School of Humanities and Social Science.

My research focuses on the relationships between kinship, inequality, and demographic behavior. I have published extensively on family, population, and stratification in eighteenth and nineteenth century northeast China, most notably the book Fate and Fortune in Rural China with James Lee. With James Lee, I am currently working on a book tentatively titled Genealogy and Inequality examining interactions between kinship, inequality, and demographic behavior in Liaoning, northeast China from the seventeenth century to the present. The specific focus is on the role of kinship networks such as descent groups in creating and sustaining patterns of inequality across multiple generations. I have published on a wide variety of other topics, including economic, family and social influences on marriage, fertility limitation in historical Chinainfluence of family context in childhood on mortality in middle age and old age, ethnic identity as reflected in naming behavior, and inter-generational social mobility.

For the analysis of Liaoning, Lee and I constructed databases from eighteenth and nineteenth century population registers, the China Multigenerational Panel Dataset-Liaoning (CMGPD-LN) that we have released publicly at the Inter-university Consortium for Political and Social Research (ICPSR) with support from the National Institute of Child Health and Human Development (NICHD) with funds from R01 HD057175-01A1 (Lee PI). With support from NICHD 1R01HD070985-01 (Campbell PI), we are in the midst of releasing a second database we have constructed for Shuangcheng county in Heilongjiang province in northeast China: the China Multigenerational Panel Dataset-Shuangcheng (CMGPD-SC).

I am also active in efforts to promote the use of household register data from various settings in East Asia to carry out comparative studies within that region.  One key focus has been to promote connections among researchers working with East Asian historical household register data.

I collaborate with Lee and other members of the Lee-Campbell research group on a variety of other projects, including a study of demographic behavior and stratification in the Qing Imperial Lineage; family organization, demographic behavior, and inequality in a frontier population, Shuangcheng, Heilongjiang; access to elite education in China since 1949; and a new study of official careers in the Qing bureaucracy as recorded in the 縉紳錄. This work is funded with an RGC GRF.

I am also a participant in the Eurasia Project, an international collaboration that compares relationships between economic conditions, household organization, and demographic behavior for a variety of historical European and Asian communities. I am a co-author of the first volume from this effort, Life Under Pressure, published in 2004 by MIT Press, that examines how household responses to economic stress were reflected in mortality patterns. I also participated in the second volume, Prudence and Pressure, which was published in 2010, and in the third volume, Similarity in Difference, which focuses on marriage and will be published in 2014 by MIT Press.

My honors include a Guggenheim Fellowship awarded in 2004, and an Award for Outstanding Book on Asia for Life Under Pressure from the American Sociological Association Section on Asia and Asian America.

In my spare time, especially when I travel. I like to take pictures. Please visit my photography site. You can also browse my list of galleries, organized by location, or see a selection of my absolute favorite photos.
