Areas of Expertise
Cancer immunology; immune tolerance; endoplasmic reticulum chaperones in cancer biology and therapy.

Dr. Zihai Li is a board-certified medical oncologist and an expert in the field of cancer immunology, chaperone biology and hematopoietic stem cell transplantation. His research group has made fundamental contributions in the area of GP96/GRP94. They discovered the ATPase activity of GP96, proved its roles in chaperoning antigenic peptides, genetically mapped a majority of its key clients (including multiple Toll-like receptors, integrins, Wnt co-receptor LRP5/6, GARP, CD91 and GP-Ib-IX-V complex), pinpointed its client-binding domain, established its co-chaperone CNPY3, and illuminated its functions in several key biological processes (hematopoiesis, innate immunity, tolerance, anti-cancer immunity, oncogenesis, etc.).  Dr. Li is the principal investigator for multiple Research Project Grants (R01s), as well as a Research Program Project Grant (P01) from the National Institutes of Health. He is a clinical scholar of the Leukemia and Lymphoma Society and an elected member of the American Society of Clinical Investigation.

The current work of the Li laboratory focuses on developing better immunotherapeutics in the forms of antibodies, adoptive T cell transfer and immune checkpoint blockers, aiming to reverse and reprogram the tolerogenic tumor microenvironment for cancer cure. Fundamental mechanisms of immune regulation are being studied in parallel.

Mentoring Philosophy
Dr. Li strongly values team science and has conducted most of his work collaboratively. Mentorship and education are cornerstones in Dr. Li’s laboratory. Since 1999, he has mentored 59 trainees and faculty (1 MS student, 26 PhD students, 3 MD/PhD students, 15 Postdoctoral Fellows, 1 MD, 4 Clinical Fellows and 9 junior faculty). Fourteen of his former mentees currently hold academic faculty positions with active research career components. Dr. Li received the Peggy Schachte Research Mentor Award, the MUSC’s top honor for outstanding research mentorship in 2016.

Members of Dr. Li’s laboratory take pride in sharing their expertise with trainees at all levels including graduate students, medical residents, clinical fellows and postdoctoral fellows. Trainees are expected to be original and hardworking, independent and interactive. They are encouraged to choose projects under the general conceptual frame in the laboratory and are expected to function at a high level.
