Prof. Ching-Ray Chang received the B. S. degree in Physics from National Taiwan University, Taipei, Taiwan, in 1979, then Ph.D. degree in Physics from University of California, San Diego, in 1988.

He was associated with magnetic group of Industrial Technology Research Institute at 1988. Since 1989, he has been with National Taiwan University. Prof. Chang has worked in micromagnetic numerical modeling since 1980s. He not only carried out pioneering static studies of micromagnetic structures in the early 80s but also was one of the first to apply the Landau-Lifschitz equation to sub-nanosecond analysis in the 1990s. Prof. Chang has made very significant scientific contributions and had great impact on the understanding of nucleation, spin dynamics and thermal activation of magnetic materials, also recently spin transport in low dimensional materials. He was the president of Asia Union of Magnetic Societies (AUMS) and Director of the Center for Theoretical Physics in NTU. He also served as Presidents of both Taiwanese Physical Society and Taiwan Associations of Magnetic Technologies. He is both APS and IEEE Fellows. He has authored more than 280 papers published and held more than 30 magnetic related patents.

Currently he is director of NTU-IBM quantum computer hub and also the Chair of quantum computer promotion office, MOST.
