Chris Xu is the IBM Chair Professor of Engineering, Cornell University. He currently serves as the Director of School of Applied and Engineering Physics, the Mong Family Foundation Director of Cornell Neurotech – Engineering, and the Director of Cornell NeuroNex Hub, an NSF funded center for developing neurotechnology. His research areas are fiber optics and biomedical imaging, with major thrusts in multiphoton microscopy for deep brain imaging, multiphoton microendoscopy for clinical applications, and fiber-based devices and systems for telecommunications and optical imaging. Prior to Cornell, he was a Member of Technical Staff at Bell Laboratories. His main research focus at Bell Labs was on nonlinear imaging of semiconductor devices, fiber optics, and optical communications, including broadband access and ultralong haul transmission. He received his Ph.D. in Applied Physics, Cornell University, and his B.S. in Physics from Fudan University. Dr. Xu has chaired or served on numerous conference organization committees and NSF/NIH review panels. He currently serves on the NIH NEI External Scientific Oversight Committee of the Audacious Goal Initiative and the OSA Biomedical Congress Strategic Planning Committee. He served as Associate Editor for Biomedical Optics Express, and is on the editorial boards of several journals. He has published 8 book chapters and more than 150 journal papers (> 12,000 total citations, ISI Web of Science), and contributed more than 170 conference papers. He has delivered over 300 invited conference presentations, research seminars, and outreach talks. He holds 25 patents on optical communications and imaging. He has won the NSF CAREER award, Bell Labs team research award, and the Tau Beta Pi and two other teaching awards from Cornell Engineering College. He received Cornell Engineering Research Excellence Award in 2017. He is a fellow of the National Academy of Inventors, and a fellow of the Optical Society of America.
