Ernst Schrama is an associate professor at the Department of Space Engineering, faculty of Aerospace Engineering at the Delft University of Technology. He obtained his MSc and his PhD degree at the Delft University of Technology, as a PostDoc he was visiting scientist at the NASA Goddard Space Flight Center. Other positions were visiting scientist at WL|Delft Hydraulist and the GRGS in Toulouse.

He has published 62 peer reviewed papers either as author or co-author in international journals and is or has been principal investigator for several projects funded by the European Space Agency, the Netherlands Organization for Scientific Research and other organisations such as the European Union. His research interests are on satellite orbit determination, satellite altimetry for modelling ocean tides, satellite gravimetry mission like GOCE for mapping the static gravity field of the Earth, and GRACE for measuring ice sheet mass change in combination with radar and laser for cryospheric applications.

Teaching activities started 30 years ago both in the BSc and the MSc curriculum of the faculty of aerospace engineering, the faculty of civil engineering and the faculty of geodesy. Currently he is involved in MSc courses on Planetary Sciences and Satellite Orbit Determination, and a BSc course of Satellite Tracking and Communication.
