Dr. Lu is an infectious disease physician scientist. While her clinical service is centered at Parkland, she spends most of her time in lab with a long-standing interest on the host relationship with microbes. Her doctoral work in molecular virology focused on innate immune signaling in the context of viral infections. Motivated by the global health burden of tuberculosis (TB) and captivated by the persistent relationship between the bacterium Mycobacterium tuberculosis (Mtb) and humans, her postdoctoral work turned toward TB through the lens of humoral immunity. She showed divergent immunoglobulin profiles in patients with clinically well characterized Mtb infection and TB disease states, highlighted by differential antibody glycosylation and effector functions. Moving beyond the clinically well-established states of Mtb infection and TB disease, she demonstrated that individuals highly exposed to Mtb yet not captured by current clinical diagnostics have developed adaptive immune responses to Mtb. These observations provide immunological parameters to broaden the definition of human Mtb infection and provide an additional perspective through which the host response to Mtb can be examined. Beyond TB, the study of antibodies in infectious diseases helps construct a more in-depth framework to understand how the landscape of humoral immunity mediates the interface of host microbial interactions, and creates paths towards biomarker and vaccine development. The long-term goal is to translate observations from humans to models of disease in order to further inform and direct human studies, realizing the remarkable potential in the synergy between science and medicine.
