Biography
Félix Sauvage was born in Dieppe (France) on the 16th of April 1987. He received his pharmacy degree (Pharm.D) in 2013 at University of Rouen Normandie, France. The same year, he obtained his Master’s degree in Pharmaceutical Technology and Biopharmaceutics at University Paris-Saclay and a fellowship from the French Ministry of Higher Education and Research. He joined the Institut-Galien Paris-Saclay (University Paris-Saclay, France) for a PhD where he worked on the formulation of liposomes for enhancing the delivery of heat shock protein inhibitors to tumours. In 2017, Félix Sauvage joined the Laboratory of General Biochemistry and Physical Pharmacy headed by Prof. Stefaan De Smedt at Ghent University as a postdoctoral research scientist with a major focus on nanotechnology and photonics in ophthalmology. Since 2017, the use of pulsed-lasers in combination with light absorbing nanoparticles for the treatment of corneal and vitreous diseases has been his major focus. In 2022, Félix was appointed assistant professor in pharmaceutical technology at Lille University, France. Later the same year, he obtained an ERC starting grant (‘DYE-LIGHT’) to investigate the use of light in combination with dyes for drug delivery and laser-based surgery in the eye at Ghent University in the Laboratory of General Biochemistry and Physical Pharmacy.
Since 2023, Félix Sauvage is associate professor at the faculty of pharmaceutical sciences in Ghent University where he is team leader (Cornea/Vitreous) within the Ocular Delivery Group led by Prof. Katrien Remaut. He is author of several peer-reviewed scientific publications (in Advanced Materials, Nature Nanotechnology, ACS nano and the Journal of Controlled release) and inventor of several patents. His early-career achievements have been recognized by several organizations. In 2019, he received a young investigator award from the European Association for Vision and Eye Research (EVER). In 2020, Félix received the AMIFAC award of the French Academy of Pharmacy for his work on the use of pulsed-lasers and nanoparticles for the destruction of vitreous opacities.

Research Topics
The research of the Cornea/Vitreous team focuses on enhancing drug delivery to the ocular surface (i.e. cornea, conjunctiva, limbus) and throughout the vitreous using specific nanocarriers and external stimuli (e.g. light or ultrasounds). Various formulations and particles are investigated and designed for this purpose (LNPs, carbon dots, nanogels…) either for passive or light-assisted drug delivery (e.g. through photoporation; Figure 1).

In parallel, the team also works on light-based techniques to improve laser assisted surgery in the posterior segment. The team is exploring the destruction of vitreous opacities (‘eye floaters’) harnessing the mechanical forces released upon implosion of vapor nanobubbles which are generated upon irradiation of plasmonic (e.g. gold nanoparticles) or light-absorbing nanoparticles and dyes (e.g. indocyanine green; Figure 2). Besides collaboration within Ghent University, the team cooperates with various partners around the world among which the Kellogg Eye Center (Prof. Yannis Paulus; Michigan University, USA), the VMR institute (Dr. J. Sebag; USA) and the University of Lille (Prof. M. Baudoin; France).
