Research Interests：	Cheng-Maw CHENG earned his Ph.D. from the Department of Physics at National Tsing-Hua University, Hsinchu, Taiwan in 2002. Following his doctoral studies, he dedicated four years to military service as a project-oriented associate research scientist at the National Synchrotron Radiation Research Center (NSRRC) in Taiwan. Upon completing his service, he joined NSRRC as a staff scientist in 2007 and currently holds the position of Research Scientist and Group Leader of the Condensed Matter Physics Group at NSRRC. Furthermore, he serves as a spokesperson and oversees two angle-resolved photoemission spectroscopy (ARPES) beamlines, namely TLS BL21B1 and TPS 39A. His research focus encompasses the investigation of the electronic structure of emerging quantum materials, including topological materials, graphene, 2D materials, and complex oxides. With over 20 years of experience, he has played a pivotal role in the development and operation of large scientific instruments.
