Igor Ying Zhang

Professor at Fudan University | Deputy Director, RCCT

Igor Ying Zhang

Prof. Igor Ying Zhang holds dual PhDs from Xiamen University and KTH (Sweden), did postdoctoral research at the Fritz Haber Institute (MPG, Germany), and became an independent group leader. He has authored 80+ papers, published the first monograph on doubly hybrid functionals (A New-Generation Density Functional, Springer), and received the NSFC Distinguished Young Scholar Award and the CCS Youth Award in Theoretical Chemistry.


Research Focus

Developing high-accuracy density functional theory methods and software for challenging chemical problems.

  • Doubly Hybrid Functionals (xDH & R-xDH): Principal founder of XYG3-type functionals achieving chemical accuracy for main-group and strongly correlated systems.
  • Cross-Entropy Corrected MC-PDFT: A generalized hybrid multiconfiguration pair-density functional theory (HMC-PDFT) for strong correlation, delivering CASPT2-level accuracy at CASSCF cost.
  • High-Performance Software: Led the development of REST, the first Rust-based electronic structure package.
