I like to work on interdisciplinary tasks. My current research deals with electrical 3D impedance tomography (EIT). From this, process variables in various technical applications can be derived in real time. My former reseach during my PHD dealed with parallel real-time simulation of mechatronic systems in hardware-in-the-loop applications for the automotive industry. Through this work I have acquired my competences in the fields of modelling, measurement technology, signal filtering, hardware near programming, electronics, FPGAs and numerical methods. I love programming to solve any kind of problem and to speed up or optimize work processes. For this I mainly use Python, C++ or Matlab. An other passion of mine is working on the best possible graphic representation of data of any kind, mostly done with Python.

Abstract: With more and more complex electronic control units (ECU) in modern automotive applications the need for adequate testing possibilities rises. This paper presents a hardware-in-the-loop (HIL) test implementation for ECUs with very high dynamic capabilities. Based on real time parallel analog and digital simulation it is able to process pulse width modulated (PWM) signals with up to 25 kilohertz with step sizes of 385 nanoseconds. The simulation’s digital output signal drives newly developed power electronics, processing the high dynamic simulation results with a resolution of 1 milliampere and a current change rate of 6.4 ampere per microsecond. In addition generic simulation models of different loads are developed.
