Let me introduce myself.

Profile Picture

I have been studying and working in the Karlsruhe area for more than 15 years. I have a diploma degree as well as a masters degree in Sensor System Technology from the University of Applied Sciences Karlsruhe and did my masters thesis in elctrochemistry at the company Bürkert Fluid Control (France). After that, I worked one year for a start-up company Sensolute GmbH as a develpoment engineer for micro technology and sensors before I switched to academia. First, I started as an engineer and Scientific Assistant in the field of metrology and automation technology at Karsruhe Institute of Technology before doing my PhD at the Institute for Photon Science and Synchrotron Radiation working interdisciplinary in the field of applied physics, X-ray imaging, mechatronics, and materials science. On February 3th 2021, I successfully defended my PhD work at Albert-Ludwigs-University of Freiburg, Freiburg Material Research Center. Since August 2021, I have been working as a Product Manager - Research, Development and Innovation for enameled metrology at Pfaudler GmbH. In addition, I am a part-time lecturer for Radiation Sensors and Detektors in the Master's Program of Sensor Systems Technology at the University of Applied Sciences Karlsruhe
