A minisymposium in honour of Professor Xinzhi Liu’s 70th birthday, “Hybrid Dynamical Systems, Control, and Applications,” was held at the Third Joint SIAM/CAIMS Annual Meetings (AN25) in Montréal to celebrate his pioneering contributions to hybrid dynamical systems over the past four decades. A member of the department since 1990, Prof. Liu has advised many students who now hold faculty positions at leading research universities and key roles in industry. Featuring eight presentations, the two-part event showcased advances at the intersection of hybrid systems, control theory, and their applications, with invited speakers from academia and industry presenting new theoretical, computational, and applied perspectives. The minisymposium was co-organized by Applied Math Professor Jun Liu, along with Professors Peter Stechlinski (University of Maine, U.S.) and Kexue Zhang (Queen’s University, Canada), both alumni of Applied Mathematics.
