Alessio Lugnan received a Master's degree in Experimental Physics from the University of Trento in 2016. He joined the Photonics Research Group (Ghent University / Imec) in 2016 as a PhD student, working on optical solutions for machine learning classification of particles for imaging microflow cytometry and on integrated photonic reservoir computing using ring resonators. He received a PhD in Photonics Engineering in 2021 and is currently working as a postdoctoral researcher in the same group, on neuromorphic computing with silicon photonics and phase change materials.
