Prof. Yunzhong Shen received his B.S. and M.S. from Tongji
University in 1983 and 1986, respectively, and his Ph.D. in geophysical geodesy
from the Institute of Geodesy and Geophysics, Chinese Academy of Sciences,
Beijing, China, in 2000. He is now a professor at the College of Surveying and
Geo-informatics, Tongji University, Shanghai, China. His research interests
include geodetic data processing on satellite positioning and satellite
gravimetry. His main research works include the regularized solution to the
ill-conditioned inverse problem of recovering a gravitational potential model
from satellite-to-satellite tracking data and variance component and parameter
estimation theory in mixed-integer models of multisystem and triple-frequency
global navigation satellite system (GNSS) observations. Dr. Shen is an Editor
of the Journal of Geodesy and Acta Geodetica et Cartographica Sinica.
