Expert in spacecraft systems engineering, dynamics, and control, and a leading figure in the fields of deep space exploration and high-orbit high-resolution remote sensing satellites. He has achieved systematic and groundbreaking results in the theoretical methods and practical applications of multi-gravity field orbital dynamics and control, high-orbit micro-vibration environment optimization control, and complex system coupling dynamics and control. He has led or participated in the development of multiple major national aerospace projects, including the "Chang'e-4," "Gaofen-4," and "Ziyuan-1" missions. He has successfully resolved a series of critical technical challenges, such as orbital design and control under the complex constraints of humanity's first-ever landing on the far side of the moon, as well as achieving high-quality imaging for the world's first high-orbit high-resolution remote sensing satellite. He has made outstanding contributions to major projects such as China's lunar exploration program and the high-resolution earth observation system. He has been awarded two Grand Prizes, one First Prize, and one Third Prize of the State Scientific and Technological Progress Award, two First Prizes of the Ministerial Level Scientific and Technological Progress Award, and one Second Prize of the National Defense Technology Invention Award.
