Dr. Jiesu Wang received her B. S. degree from Minzu University of China in 2013 and Ph. D. from Institute of Physics, Chinese Academy of Sciences (IOP, CAS) in 2018. From 2018 to 2020, she worked as postdoctor in Key Lab. for Optical Physics in IOP, CAS. Thereafter, she joined BAQIS as the Assistant Research Scientist of the Low-dimensional Quantum Materials team leading by Kai Chang. Dr. Wang is devoted to using optical technology to explore the physical properties of low-dimensional materials, especially the Second Harmonic Generation (SHG) technology.

Research Interestes

· SHG and other nonlinear optical properties from low-dimentional materials.

· Using SHG to explore the point group\ferroelecticiy\antimagnetism in low-dimentional materials.

· Exploring the mechanism of regulating the physical properties of low-dimentional materials and their heterostructures as a function of temperature, magnetic field, chemical doping, electrostatic field, etc.
