David has a PhD degree in electronics from Mid Sweden University with a focus on the simulation of hybrid pixel detectors and neutron detectors. Now he is working with in the Milo project with X-ray systems for environmental monitoring.
David Krapohl has an engineering degree in mechatronics from Aachen University of Applied Sciences, Aachen, Germany. Half a year was a student exchange at Mälardalen University, Sweden.
Before coming to Sweden he worked as a research engineer at the University of Lübeck in the field of neuroscience (FEM simulation).
