My research experiences in condensed matter physics started from 2007 as a PHD student in Institute of Physics, Chinese Academy of Sciences. During my PHD, supervised by Prof. Hai-Hu Wen, I mainly focused on the investigations in Fe-based superconductors. The research works includes the discovery of GdFeAsO1-xFx superconductor, the first successful ambient growth and characterization of FeAs-1111 superconductors. Since I joined Prof. Wei Bao’s group in Renmin University of China I have been in charge of the design and construction of XingZhi triple-axis spectrometer at China advanced research reactor. After the acceptance of XingZhi in 2019, I have been responsible for the scientific experiments and maintenance of XingZhi. Up to 2024, there have been 11 research articles published based on the experiments on XingZhi. Now our group also focuses on the material exploration, single crystal growth and physical properties on magnetic quantum materials. In recent years, we have discovered several new magnetic 2D materials includes Co-doped Fe5GeTe2 and FePd2Te2, as well as many research progress in other quantum magnets such as Kagome metal FeGe1-xSbx and sawtooth lattice magnet Fe2SiSe4. I have published over 60 SCI research articles with total citations over 3000 times.
