       I mainly investigate the structures, phase-transition kinetics, and mechanical, electrical, optical, thermal, and magnetic properties of geological materials, metals, alloys, and other advanced materials under extreme high pressure-temperature conditions. At Sichuan University, I have established a high-velocity impact and high-pressure physics experimental platform, equipped with one- and two-stage light-gas guns, diamond anvil cells, and other related facilities, as well as diagnostic systems with high spatial and temporal resolution. The platform enables a wide range of experiments, including recovery experiments and microscopic characterization under high-pressure and high-temperature conditions, phase-transition diagnostics, equation-of-state measurements, elasticity and sound-velocity measurements, electrical and thermal conductivity measurements, and dynamic damage and fracture experiments. We also provide high-velocity impact testing services (0–6 km/s), in situ physical measurements under high-pressure and high-temperature conditions, and laboratory construction services for extreme-condition physics research to universities, research institutions, and industrial enterprises.

      Our major researches focus on extreme-condition physics, including:

       1. Extreme high-pressure mineral physics: We investigate the structures and physical properties of minerals and geological materials under extreme conditions, aiming to elucidate the physical and dynamical processes operating in the interiors of Earth and other planets and to explore the connections between planetary interior dynamics and surface habitability.

       2. Extreme high-pressure physics and mechanics: We investigate the equations of state, phase transitions, phase-transition kinetics, and shock-dynamic behavior of condensed matter, including metals, ceramics, and functional materials, under high-pressure and high-temperature conditions, with applications to advanced materials and industrial technologies.

      The research group recruits 2–3 direct-entry Ph.D. students and integrated M.S.–Ph.D. students each year. Students with backgrounds in physics, mechanics, Earth and planetary sciences, aerospace and aeronautics, materials science, and other related science and engineering disciplines are welcome to apply. Ph.D. graduates who meet the academic requirements of the research group may be recommended for employment after graduation.
