Paulo Coelho graduated in chemistry from the University of Lisbon in 1991. He received the Diplôme d¿études approfondies (1992) and the PhD (1995) in Chimie Organique from the Université de Paris-sud, Orsay. In 2015 he obtained the Habilitation degree from the University of Trás-os-Montes and Alto Douro for his research and teaching work in the field of organic chemistry, where he is Associated Professor since 2002 . He was the coordinator of CQ-VR research unit from 2013 to 2019 and actually he is the Vice-president of the Scientific Council of the ECVA school (2021-2025). Present investigation interests are focused on the synthesis of photochromic compounds, characterization of their behavior under light exposure and application in textiles, ophthalmic lenses, and more recently to act as photoinitiators of radical polymerization for the production of solid objects or deposition on surfaces. He coordinated 6 research projects on these subjects, including two with a lens manufacturer and participated, as an active researcher, in 3 other ones. He has published more than 78 papers in organic chemistry journals and 3 patents. He is a regular reviewer of different scientific journals and in the last 6 years he made 139 peer reviews.
