Philippe Robert defended his Habilitation à Diriger des Recherches on February the 14th, 2025. He presented his work on the measurement of kinetics of TCRs and antibody-antigen bonds at the single molecular level under physiological forces, with numerous methodological developments that accompanied it. He also described medical applications of the method, with results regarding the quantification of leukocyte-endothelium interactions during inflammation and thrombosis. Finally, he presented the current state of development of microprinted assays for quantification of leukocyte functions that he patented with Olivier Theodoly, that aim to bring to routine use for patients functionnal assays that are currently too slow and expensive to be used in the hospital.
