Hongjie Liu
Dr. Liu’s research focuses on the social and behavioral aspects of HIV/AIDS, infectious disease epidemiology, and research methodology. His expertise includes social and risk network analysis for HIV transmission, stigma and intervention research, epidemic modeling, survey methodology (e.g., sampling hidden populations), and advanced analytic methods such as association modeling, structural equation modeling, actor–partner interdependence modeling, and psychometric analysis.
Since 1997, Dr. Liu has served as Principal Investigator, Co-Principal Investigator, or consultant on 13 HIV-related studies in China, 12 in the United States, and 2 in Nigeria. He has received research funding from the National Institutes of Health (NIH) (as PI on R03, R21, and R01 grants), the National Science Foundation (NSF), the Foundation for AIDS Research (amfAR), the International Society for Infectious Diseases (ISID), the UCLA AIDS Institute, and other agencies. He has authored 122 peer-reviewed publications (h-index: 41; i10-index: 92), including 103 in English-language journals and 19 in Chinese journals.
