CV
Mathias Ibsen received his M.Sc. in Engineering, Artificial Intelligence and Algorithms from the Technical University of Denmark (DTU) in 2020. Subsequently, he became a PhD student member of the da/sec group at Faculty of Computer Science, Hochschule Darmstadt, Germany. He works on the EU-funded TReSPAsS-ETN project with the detection of manipulated face images.
