Dr. Qi is a Professor in Immunology at Tsinghua University. He studies humoral immune regulation and germinal center biology. His group has made important contributions to our understanding of molecular mechanisms underlying T-B interactions, follicular helper T-cell development and function, and germinal center positive selection. His group has also made important advances in mechanistic understanding of sexual dimorphism in B-cell immunity and how brain can directly control antibody responses. Dr. Qi is an HHMI International Scholar and has been recognized by numerous awards, including an AAI-BD Investigator Award.
