Hou Xiyun serves as an associate professor and doctoral supervisor at the School of Astronomy and Space Science. He received his bachelor’s degree in 2003 and doctorate in 2008 from the Department of Astronomy at Nanjing University. In 2011, he was awarded the National Excellent Doctoral Dissertation Award for his dissertation “The Dynamic and Application of Lagrangian Points.” In the same year, he was named a New Century Excellent Talent by the Ministry of Education. In 2013, he was supported by the Excellent Young Scientists Fund of the National Natural Science Foundation.

His research focuses on spacecraft orbital mechanics and dynamics of small celestial bodies in the solar system. He has participated in the top-level demonstration of China’s lunar exploration phase III, the research on the concept of manned lunar landing and the pre-research of Mars exploration.

As of now, he has published more than 30 SCI papers, led four national projects, participated in one key project supported by the Joint Fund of Astronomy, one supported by the 863 program, and one supported by the 973 program, and he has participated in more than ten national- and provincial-level space projects as the principal project leader. From January 2013 to December 2014, he made an academic visit to the department of aerospace science and engineering at University of Colorado Boulder. He is currently researching asteroid detection.

He teaches Fundamentals of Orbital Design (undergraduate students, elective course, two credit hours) and Orbital Mechanics (graduate students, core course, four credit hours)
