Jun Zhang received the Ph.D. degree in optics from Shanghai Jiaotong University, China, in 2001. He is currently an Assistant Project Scientist in the Beckman Laser Institute at the University of California, Irvine. His research experience and interests are in the areas of development of optical coherence tomography (OCT), fiber-optic endoscopy and translation of these techniques to address clinical problems. Dr. Zhang has published more than 50 peer reviewed technical papers and multiple patents. He is currently Principal Investigator for two studies: an NIH grant designed to evaluate obstructive sleep apnea with long range 3D endoscopic FDOCT; a California Tobacco-Related Disease Research Program (TRDRP) supported grant to combine high speed 3-D imaging techniques with the surgical laser into a system for detection and treatment of smoke induced cancer.
