Professor Xu joined Cornell faculty in the fall of 2002. Prior to that, he was a member of technical staff in Advanced Photonic Research at Bell Laboratories from 1999 to 2002. He joined Bell Laboratories as a postdoctoral member in 1997. Professor Xu received his Ph.D. from Cornell in the department of Applied and Engineering Physics in 1996, and earned his B.S. in physics from Fudan University in Shanghai. He is the recipient of the 2004 Tau Beta Pi Teaching Award, presented by the Cornell Society of Engineers. He was a recipient of the College of Engineering Teaching Award in 2005 and 2008. Besides technical publications, he has 28 patents granted or pending. He is a fellow of the National Academy of Inventors, and a fellow of the Optical Society of America.
Our research has two main thrusts: biomedical imaging and fiber optics. We are exploring new concepts and techniques for in vivo imaging deep into scattering biological specimens, such as mouse brain. We are developing new medical endoscopes for non-invasive real-time diagnostics of tissues without any exogenous contrast agent. We are developing novel optical fibers and fiber-based devices for biomedical imaging and optical communications.
