Short Biography

Dr. Charles Webb joined the Cryospheric Sciences Lab in June 2010 to support the design and development of the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) mission.

He graduated Tau Beta Pi from Cornell University, earning a B.S. in Mechanical and Aerospace Engineering. Subsequently, he joined the Edison Engineering program at General Electric, holding positions in mechanical systems, propulsion systems design, and mission design and analysis. While there, he earned an M.S.E. in Systems Engineering from the University of Pennsylvania. He continued to serve as a senior engineer, at what had become Lockheed Martin, until returning to graduate school at the University of Texas at Austin, where he earned a Ph.D. in Aerospace Engineering, with an emphasis on dynamic modeling for precision orbit determination. After graduating, he held a joint postdoctoral fellowship with the university’s Center for Space Research and Institute for Geophysics, working to improve the geolocation accuracy of laser spots during the original ICESat mission, and using the altimetry data collected to evaluate ongoing changes in the glaciers and ice caps of Arctic Canada.
