Tutorial Introduction

Prof. Dr.  Shuiquan Deng

Prof. Shuiquan Deng was awarded the Ph. D degree by the Fujian Institute of Research on the Structure of Matter (FJIRSM), Chinese Academy of Sciences in 1992. He was appointed an assistant professorship and an associate professorship at FJIRSM in 1992 and 1995, respectively. From 1995 to 1996, he worked in the University of Geneva as a postdoctor. From 1996 to 2014, he had worked in Max-Planck-Institute for Solid State Research at Stuttgart as a guest scientist in the first two years, and then a theoretical group leader of Abt. Simon at the BAT-IIa and BAT-Ib staff scientist position, respectively. Since 2014, he has been appointed a full professorship and PI at FJIRSM through the "100 talents program" of FJIRSM, Chinese Academy of Sciences. His research activities involve in the analytic and numeric studies on the relations between multi-scale structures of solid state materials and their properties such as superconductivity, optical, multiferroic and symmetry/topology dependent properties.

Research Field
