Dr. Susan Kaech is a Professor and Director of the NOMIS Center for Immunobiology and Microbial Pathogenesis at the Salk Institute. Her lab aims to understand how memory T cells are produced during infection and vaccination, how they function, and why they can fail to induce long-term immunity, particularly during chronic disease or cancer. In this episode, she talks about her research on T cell exhaustion and neuroimmunology, as well as her path from genetics to immunology.
