About

Lei Wang’s research focuses on geodesy, the science of measurement of the size, shape, rotation and gravitational field of the Earth. He obtained his Ph.D in geodetic science from The Ohio State University in 2012. His Ph.D thesis is about the quantification of earthquake deformation using gravity satellite GRACE (Gravity Recovery And Climate Experiment). As a postdoctoral research scientist at the Lamont-Doherty Earth Observatory of Columbia University, he worked on the integration of multiple types of geodetic data (satellite gravity, tide gauge, GPS, satellite altimetry) for simultaneous estimation of temporally and spatially variable ice mass melting and glacial isostatic adjustment. In 2014, he worked at the Department of Earth, Atmospheric and Planetary Sciences, MIT on high-precision GNSS (Global Navigation Satellite System) static and kinematic positioning.

Lei Wang specializes in acquiring, analyzing and interpreting space-based geodetic observation, such as GNSS and satellite gravity. He is interested in the application of various geodetic measurements in the engineering and scientific problems over a range of spatial and temporal scales, including:

  • High-precision GNSS positioning and navigation
  • Crustal deformation associated with earthquake, plate tectonics and volcanos
  • Sea level changes
  • Hydrology and continental water storage
  • Ice mass balance, and motion of glaciers
