Current Research

  • Professor Ji Wei’s research interests cover nonlinear optics and ultrafast nonlinear spectroscopy, for nonlinear optical and quantum materials which have photonic and optoelectronic applications. He has co-authored over 230 research papers, and his h-index is above 50. Recently, his research interests have been extended to optoelectronics with 2D materials and metal-organic frameworks.
