We are pleased to announce that Chris Xu, the IBM Professor of Engineering, has been reappointed to a two-year term as Director of the School of Applied and Engineering Physics, effective July 1, 2026.
“Chris was first appointed to this position in 2020. He has provided the School with steady, strategic leadership and he has been a valuable contributor to the broader College community, serving as an effective and capable partner with a compelling vision for the future. He is also an excellent scientist and educator. Known for the development of temporal focusing and long-wavelength two- and three-photon microscopy for deep-tissue imaging, his work has found applications in fiber optics and optical imaging, with major thrusts in deep-tissue imaging, laser development, and smart and efficient optical imaging. He holds more than 25 patents on optical communications and imaging, and his work has been recognized with numerous awards. He is a fellow of both Optica (formerly the Optical Society of America) and the National Academy of Inventors.”
