Zhengwei LI, Research Professor of Institute of High Energy Physics, Chinese Academy of Sciences. He is mainly engaged in the research and development of astronomical instruments, including space X-ray detection technology and cosmic microwave background radiation detection technology. He conducts research on transition-edge sensor detectors and cryogenic readout technology, such as low-temperature superconducting quantum interference devices (SQUID). He served as the chief designer of the high-energy in-orbit calibration detector onboard China's first space X-ray astronomical satellite, Insight-HXMT. He has successively participated in multiple space projects such as the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM), the enhanced X-ray Timing and Polarimetry Mission (eXTP), the Wide-band X-ray Spectroscopy and Polarimetry Telescope (WXPT) — a conceptual space X-ray telescope, and the All-sky Transient Hunter Constellation (CATCH). He serves as the Chief Engineer of Ali Primordial Gravitational Wave Experiment, and pioneered the research and development of CMB low-temperature superconducting detection technology in China. He is the Principal Investigator of the key R&D project of Ministry of Science and Technology, entitled “Research on Core Technologies of Focal Plane Detectors and Antennas for Primordial Gravitational Wave Telescopes”. He has presided over a number of research grants, including equipment development projects of Chinese Academy of Sciences, the Young Scientists Fund and the Joint Astronomy Fund of National Natural Science Foundation of China.
