After completing his doctorate, postdoctoral studies and two years in industry, he founded his engineering firm in 2005.
Volker gained extensive experience in technical optics in numerous projects ranging from deep underground (borehole monitoring with fibre optics) to outer space (satellite-based optics). His area of expertise is working with ZEMAX®, a software programme that he has been using almost daily since 2004 and which continues to inspire him.
Another area of his work is computer-aided data analysis, a subject that has fascinated him since his student days and in which he can combine his knowledge of physics, mathematics and computer science.
