Yuzuru Takashima is an Associate Professor at College of Optical Sciences of University of Arizona and has been on the faculty since 2011. He teaches one of the core courses: Lens Design for undergraduates and Optical Design for Multi-scale Photonic System for graduate students. Prior to joining to the University of Arizona, he was employed as a research staff by Stanford University, where he has been actively involved in the field of novel optical system design and engineering, particularly for high density page-based and bit-based holographic data storage systems and Nano-photonic electron beam generators. He was employed as an optical engineer at Toshiba Corporation in Japan, where he conducted research and development of ultra-precision manufacturing of optical components and products. He received his B.S. degree in Physics from Kyoto University (1990) and M.S. (2004) and Ph.D. degrees in Electrical Engineering from Stanford University in 2007. His current research includes X-ray optical system design, environmentally robust holographic data storage system, maskbased and mask-less hybrid lithography for 3D optical interconnects, novel alignment process for lithography, ultra-thin form factor head worn display, and environmentally robust free space quantum optical communication system.
