YanluLi
Yanlu Li is a part-time professor at Ghent University and a staff member at imec. He received a bachelor's degree in applied physics from Dalian University of Technology in 2006 and the Erasmus Mundus Master's degree of Science in Photonics from Universiteit Gent, Vrije Universiteit Brussel, University of St Andrews, Heroit-Watt University and Kungliga Tekniska Hogskolan （KTH）in 2008. He obtained his Ph.D. in Photonics at Universiteit Gent, where his research topic was to realize a miniaturized Laser Doppler Vibrometer (LDV) integrated on a silicon photonics platform.

He has been involved in several research projects related to LDV, including H2020 CARDIS, H2020 InSiDe, and H2020 PhotonicLEAP.

His research interest is in photonic integrated circuit techniques used for non-contact and non-destructive sensing and imaging in various applications, including biomedical sensing and imaging, structural health monitoring, and non-destructive testing for materials and structures.
