For the Institute for Neuro-Immune Medicine's June 2026 Research Seminar Series, Dr. Michal Caspi Tal presents findings from the MAESTRO study (Measure Absolutely Everything So Tests can be Reliable and Objective), MIT's landmark clinical investigation into the shared biology of chronic Lyme disease, long COVID, and other infection-associated chronic illnesses.Dr. Caspi Tal introduces a multimodal profiling framework designed to generate the objective, reliable measures that clinical practice currently lacks — spanning eye tracking, EEG, capillaroscopy, vascular dynamics, electrical impedance, orthostatic challenge testing, whole genome sequencing, metabolomics, and more. She presents interim findings on measurable mild cognitive dysfunction, striking capillaroscopy observations including microhemorrhages and capillary dropout, and vascular changes visible in real time before and after orthostatic challenge. She also discusses her lab's mouse model of chronic Lyme, evidence linking Lyme infection to gynecological conditions and infection-induced hypermobility, and a framework for thinking about chronic illness as a cascade of "dominoes" — where identifying and stabilizing each patient's top driver enables downstream healing.

Dr. Michal Caspi Tal is an immunoengineer and Principal Scientist at MIT, where she leads the Tal Research Group in the Department of Biological Engineering and serves as Associate Scientific Director of the Center for Gynepathology Research. She earned her PhD in Immunobiology from Yale University and completed her postdoctoral training at Stanford University, where she studied immune mechanisms impacting infectious disease clearance. Her research focuses on infection-associated chronic illnesses, including Lyme disease and Long COVID, with a particular interest in how sex, hormones, and age influence immune responses and disease outcomes. Dr. Tal leads MAESTRO, the largest clinical study at MIT, which aims to develop objective diagnostics and targeted therapeutics for chronic Lyme disease and Long COVID through comprehensive clinical and preclinical research.
