"One of the main benefits of online education is the flexibility it offers to both students and instructors; students can select the topics that are of most interest to them or that are most challenging, instructors can more easily apply blended learning concepts and accomodate students having different levels or prior knowledge."

Sandra Verhagen obtained her MSc and PhD in geodesy and is now an assistant professor at the department of Geoscience and Remote Sensing of Delft University of Technology. In 2007 she received a VENI grant from the Dutch Science Foundation. From 2007 to 2011 she was the president of Commission 4 "Positioning and Applications" of the International Association of Geodesy.

In 2012 she was a visiting research fellow at the GNSS Research Centre of Curtin University, Perth in Australia. Currently, she is theme leader "Sensing from Space" of the Delft Space Institute.
