About the person

Short vita

Prof. Karagounis studied communications engineering at the Cologne University of Applied Sciences. Parallel to his first professional activities in the IT and medical technology sector, the Cologne native completed a supplementary degree in electrical engineering at the University of Hagen. As part of his doctorate, he supported the development of a readout chip for the pixel detector at the ATLAS experiment, which is installed at the world's largest accelerator, the Large Hardron Collider in Geneva/Switzerland. After completing his doctorate, Prof. Karagounis worked for the Infineon subsidiary EPOS GmbH & Co KG in Duisburg as an analog/mixed-signal designer. There, the engineer developed integrated digital voltage regulators for the supply of microcontrollers with automotive applications. Prof. Karagounis then devoted himself to the development of phase-locked loop circuits, such as those used in smartphones with navigation functionality, as a radio frequency circuit designer at Intel Mobile Communications GmbH in Duisburg. In 2013, Prof. Karagounis was appointed to a basic professorship for electrical engineering at Hamm-Lippstadt University of Applied Sciences. Prof. Karagounis has been teaching electronics at Fachhochschule Dortmund since 2016.
