Kali Zhou, MD MAS is a transplant hepatologist and Assistant Professor in the Division of Gastrointestinal and Liver Diseases, Keck School of Medicine, University of Southern California, Los Angeles, California. She received her medical degree from Feinberg School of Medicine at Northwestern University, completed an internal medicine residency at the University of California, Los Angeles, and a T32 gastroenterology and transplant hepatology fellowship at the University of California, San Francisco, where she also completed a Masters in Clinical Research. She was a Fulbright scholar and has published numerous peer-reviewed manuscripts and reviews related to epidemiology and health services delivery for chronic viral hepatitis B and C.

Her current research program focuses on disparities in liver cancer and utilizing novel geospatial approaches to combat disparities in diverse populations. She is also grant funded to study the impact of immigration and acculturation on completing guideline-based HBV metrics and to pilot a need-based Lyft-rideshare intervention to improve time to listing among liver transplant candidates. Her career goal is to develop effective, pragmatic, and efficient interventions that will ultimately improve equity and outcomes for patients with liver disease.
