Profile Summary

Dr. Shen-En Qian received his Ph.D. in 1990. He is a top government scientist and technical authority at the Canadian Space Agency. He provides leadership to industry and academia in advancing Canadian space programs. He is an internationally recognized expert in optical spacecraft payloads, space technologies for satellite missions and deep space exploration, remote sensing, satellite signal processing and enhancement, on-board satellite data compression and data handling. He has 30 years’ experience in these areas. Together with CCSDS members from NASA and other space agencies, he developed three international standards for spacecraft data systems. These standards have benefited over fifty space missions.

Dr. Qian holds 35 granted patents worldwide developed in Canadian government laboratory. He is the sole author of three books on satellite system design and signal processing: (1)Hyperspectral Satellites and System Design, (2)Optical Satellite Signal Processing and Enhancement, (3)Optical Satellite Data Compression and Implementation, and a author of chapters in five other books. In collaborating with 200 rocket scientists at national space agencies (NASA, ESA, CSA, JAXA, etc.) and PIs at leading universities, he edited and published a must-have handbook “Optical Payloads for Space Missions” in 2016. He has published over 120 scientific papers.

Dr. Qian is a fellow of the Canadian Academy of Engineering (CAE), a fellow of the International Society of Optics and Photonics Engineering (SPIE), and a Senior Member of IEEE. The Governor General of Canada awarded him the prestigious Canadian national award “Public Service Awards of Excellence" in 2016. He received IEEE Canada Outstanding Engineer Award and Silver Medal in 2019. He received the 1st prize of the Canadian Government Invention Award, and Marie Curie Award issued by the European Union. He is an Associate Editor of Journal of Applied Remote Sensing. He is an adjunct professor at York University.
