Sun began his professional career in 1984, designing aircraft electrical systems at the research and development center of the Xian Aircraft Company in Xian, China. Beginning in 1991, he spent five years at the Institute for Power Electronics and Electrical Devices at the University of Paderborn, in Paderborn, Germany. He served as a research assistant, then as a research associate, while pursuing a doctoral degree. Following completion of his degree, Sun was a post-doctoral fellow at the Georgia Institute of Technology's School of Electrical and Computer Engineering from 1996 to 1997. He then worked at the Advanced Technology Center at Rockwell Collins in Cedar Rapids, IA, as a senior engineer from 1997 to 1999. Sun was promoted to principal engineer in 2000, and became a member of the Rensselaer faculty in 2002.
