Jia Jianjun is a research fellow and doctoral supervisor at the Shanghai Institute of Technical Physics, Chinese Academy of Sciences. He graduated from Northwestern Polytechnical University with a bachelor's degree in Aircraft Manufacturing Engineering and a master's degree in Aerospace Manufacturing Engineering and received his doctor's degree in Material Processing Engineering from Shanghai Jiao Tong University. Since graduation, he has been engaged in the design of space photoelectric instruments and engineering model development for a long time. He has researched core technologies, like space photoelectric tracking and aiming systems and optical-mechanical-thermal integrated payload design, and applied for a number of patents in related fields. He has been deeply engaged in multiple space photoelectric payload model tasks, like the quantum science experimental satellite "Mozi", "Tiangong space stations", and "Chang'e lunar probes". He has held several positions, like the designer-in-charge of the quantum entanglement transmitter for the Mozi satellite, and served as the leader of several pre-research projects. At present, he is mainly conducting the engineering tasks of space active optoelectronic and quantum precision measurement and space large-aperture telescope development, while actively promoting the pre-research of space gravitational wave detection technology and the development of the space optical communication industry. He was awarded one First Prize and one Second Prize of Shanghai Science and Technology Progress Award and one First Prize of Technological Invention Award.
