Dr. Pedro Lowenstein co-chaired Tutorial T7, “Form and Functions of Topological Defects in Biological Matter,” at the APS Global Physics Summit 2026, held on March 15 at the Colorado Convention Center. The session brought together researchers across disciplines to explore cutting-edge developments at the intersection of biological physics, active matter, and mathematics. On March 18, Dr. Lowenstein also presented “Topology Control of Cancer Cell Monolayers Density by Liquid Crystal Networks” as part of the conference program. The work highlights how engineered topological defects can regulate glioma cell growth, distribution, and apoptosis, offering a novel, physics-based approach to controlling tumor behavior.
