Changhong Cao is an Assistant Professor in Mechanical Engineering at McGill University whose research sits at the cutting edge of nanotechnology, advanced materials, and manufacturing. He earned his Ph.D. from the University of Toronto and completed postdoctoral work at MIT. His lab develops novel 2D and 3D printing techniques, explores the mechanics of ultrathin materials like graphene, and builds micro-electromechanical systems (MEMS) to study how these materials behave under different forces.
