RoelBaets
Roel Baets is a full professor at Ghent University (UGent) and is also associated with IMEC, both in Belgium. He received an MSc degree in EE from UGent, a second MSc degree from Stanford University and a PhD degree from UGent. From 1984 till 1989 he held a postdoc position at IMEC. Since 1989 he has been a professor in the Faculty of Engineering and Architecture of UGent where he founded the Photonics Research Group. From 1990 till 1994 he has also been a part-time professor at TU Delft and from 2004 till 2008 at TU Eindhoven.
Roel Baets has made contributions to research on photonic integrated circuits, both in silicon photonics and in III-V semiconductors, including their heterogeneous integration. In recent years his research gradually moved to the application level, especially with focus on medical and environmental sensing.
Roel Baets has chaired the Photonics Research Group at UGent-IMEC until 2022. With 12 professors and 85 researchers this group is involved in numerous research programs and has led to the creation of 7 spin-off companies.
Roel Baets has led major research projects in silicon photonics in Europe. In 2006 he founded ePIXfab, the globally first Multi-Project-Wafer service for silicon photonics. Since then ePIXfab has evolved to become the European Silicon Photonics Alliance. He was co-founder of the European MSc programme in Photonics of UGent and VUB.
Roel Baets has been an ERC grantee of the European Research Council and a Methusalem grantee of the Flemish government. He is a Fellow of IEEE, of European Optical Society (EOS) and of Optica. He is a member of the Royal Flemish Academy of Belgium for Sciences and the Arts. He has been a recipient of the 2011 MOC award, of the 2018 PIC-International Lifetime Achievement Award, of the 2020 OSA-IEEE John Tyndall award and of the 2023 IEEE Photonics Award.
Since October 2023 Roel Baets is emeritus professor in the Photonics Research Group.
