Brief Bio


Xiaoli Sun is a Research Physical Scientist at the Planetary Geology, Geophysics, and Geochemistry Laboratory, NASA Goddard Space Flight Center (GSFC). He was the Lead Engineer in the photodetector development and receiver performance analysis for various space lidar developed at NASA GSFC, including the Mars Orbiter Laser Altimeter on the Mars Global Surveyor Mission and the Geoscience Laser Altimeter System on the ICESat Mission. He was the instrument scientist for the Mercury Laser Altimeter on the MESSENGER mission, the Lunar Orbiter Laser Altimeter, and the one-way Laser Ranging system on the Lunar Reconnaissance Orbiter (LRO) mission. He led the first two-way laser ranging experiment between the MESSENGER spacecraft and Earth over 24 million km in 2005, and the first lunar laser communication experiments from Earth to LRO at lunar distance in 2012. Recently, he has been leading the research and application of HgCdTe avalanche photodiode arrays for future swath mapping lidar and spectroscopic infrared lidar at NASA GSFC. He received the B.S. degree from Taiyuan Institute of Technology, Taiyuan, China, in 1982, and the M.S. and Ph.D. degrees in electrical engineering from the Johns Hopkins University, Baltimore, MD, USA, in 1985 and 1989, respectively.
