Zheshen Zhang
Dr. Zheshen Zhang is an Assistant Professor in the Department of Materials Science and Engineering and the College of Optical Sciences at the University of Arizona. He received the B.S. degree in Electrical Engineering from Shanghai Jiao Tong University in 2006 and the Ph.D. degree in Electrical and Computer Engineering from the Georgia Institute of Technology in 2011. During his Ph.D., Zhang split his timebetween Georgia Tech’s main campus in Atlanta and its Lorraine campus in Metz, France. Dr. Zhang joined MIT in 2012 as a Postdoctoral Associate and became a Research Scientist in 2015.

Dr. Zhang's research encompasses a broad swath of the experimental and theoretical aspects of quantum information science. Dr. Zhang studies new materials and light-matter interactions that give rise to unique quantum phenomena. These quantum phenomena are in turn leveraged in quantum-optics and nanophotonic platforms to implement devices that serve as building blocks for scalable quantum information processing. In conjunction with theoretical investigations on quantum protocols, Dr. Zhang's research gives rise to novel applications in diverse fields ranging from non-invasive sensing to telecommunications with provable security.
