Patrick pioneered the use of advanced 3D interaction and Virtual Reality in our group, dealing with a wide range of applications in medicine (heart surgery, hand and skull anatomy, liver surgery) and beyond. In particular, his work as key developer in an EU project on radiochemistry is influential. Moreover, he developed a 3D puzzle for reconstructing an essential part of Magdeburg’s cathedral – a system that is still presented in the cathedral. After nine years as PhD and Post-Doc., Patrick now extends his freelancing work that he started years ago. We wish him the best of luck for his future!
