Mark received his Master’s degree from the TU Delft Aerospace Engineering faculty, where his interest in wind energy was sparked. After working a few years for start-ups, he found his way back to the TU Delft and started a PhD. His PhD project is on airborne wind energy (AWE), in which he is developing better methods for calculating energy production metrics of AWE systems that use kites to harness the energy in the wind at high altitudes. He is using historical wind data and flight data of AWE systems to improve models of the wind resource and flight mechanics, respectively. The kites he is mostly interested in are flexible kites, i.e. scaled up versions of kite surf kites. These type of kites are also employed by the start-up Kitepower B.V., with which he is closely collaborating.
