I am an Assistant Professor in the department of Sociology at the Hong Kong Baptist University. My research interests cover Race and Ethnicity, International Migration, Social Network, Urban Sociology, and Research Methods. My dissertation investigates the relationship between national politics and migrants’ ethnic identities, contested Chinese culture across borders, and the integration experiences of both long-term and temporary Chinese migrants in Australia. I focus on how national and ethnic identities become stronger or weaker in different social settings (job-finding, workplace, community, and social life). In my dissertation I identify conditions under which national or ethnic identity is invoked at some times, but rejected at others. These conditions include co-ethnic exploitation experiences in the cash economy, internal ethnic conflict, established interaction patterns in the workplace, ethnic organizing in ethnic networks or community organizations, and racial discrimination from another racial group (white Australians).
