Asistant Researcher College of Science, Institute for Quanfum Science and Engineering   Research Group

Dr. Ke Deng is Assistant Researcher in Southern University of Science and Technology (SUSTech), China. He obtained his B.S. degree in 2013 from Xi’an Jiao Tong University, and Ph.D in 2019 from Tsinghua University. He did his research in the discovery of novel state of matter and low-dimensional quantum materials by synchrotron-based spectroscopy techniques in Advanced Light Source, Lawrence Berkeley National Lab (ALS, LBNL) after he was awarded the ALS Doctoral Fellowship from 2015-2017. He is mainly focusing on using Angle-resolved photoemission spectroscopy (ARPES) and related spectroscopic techniques to uncover the novel electronic structure of low-dimensional materials and topological quantum materials, for ultimately exploiting and manipulating their properties. In addition, Dr. Deng is also interested in accurately and quatitively control the electronic structure and excitation in quantum state of matter.
