Dr. Liu graduated from UCLA School of Public Health in 2002, with a doctoral degree in Epidemiology.

His research focuses on social and behavioral aspects of HIV/AIDS and research methodology. In the past five years, his research projects mainly covered egocentric social and risk networks for HIV infection, sexual risks, non-injection and injection drug use, stigma, survey methodology (e.g., respondent-driven sampling), and advanced analytical techniques (structural equation modeling, actor-partner interdependent modeling, and psychometric analysis). Findings from his research have generated significant impacts as the identification of multi-faceted factors for HIV infection is highly likely to provide new targets for preventive interventions.

Dr. Liu has been actively and productively involved in research activities. Since 1997, he has participated, as a PI, Co-PI, or consultant, in 13 HIV-related studies in China and 6 studies in the United States. He has continuously received research funding from NIH (as PI on R03, R21, and R01 grants), the Foundation for AIDS Research (amfAR), the International Society for Infectious Diseases (ISID), the UCLA AIDS Institute, and other agencies. So far, Dr. Liu has authored a total of 66 peer-reviewed papers, including 47 publications (h-index: 18) in English journals and 19 in Chinese journals.
