Personal Profile
Ma Chengde graduated from the Department of Physics, Fu Jen Catholic University, Taiwan, in 2007, and subsequently obtained his master's and doctoral degrees from National Taiwan University in 2010 and 2018, respectively. After completing his Ph.D., he conducted postdoctoral and research work at various research institutions in the United States, South Korea, South Africa, and China. He has been serving as an Assistant Professor at SGT University, India, since 2026, and joined HIMIS in October 2026.Ma Chengde's primary research focuses on theoretical physics, including string theory, quantum field theory, quantum information, and the holographic principle. In recent years, his research has emphasized topics such as AdS/CFT correspondence, the SYK model, quantum entanglement, quantum chaos, emergent spacetime, random matrix theory, and von Neumann algebras. His work also extends to non-Hermitian quantum field theory, de Sitter holography, defect conformal field theory, and lattice quantum field theory, dedicated to exploring the intersections among quantum gravity, quantum information, and high-energy theoretical physics.
