Hélio Barros is a junior researcher at FARM-ID working in the development of dual MDM2/X inhibitors (project PTDC/QUI-QOR/29664/2017, coordinator Maria M. M. Santos). Hélio obtained a degree in Applied Chemistry with a specialization in Organic Chemistry from Nova University of Lisbon in 2012. After successfully completing his degree, he was awarded academic merit prize with an international exchange grant financed by the Luso-Brazilian Santander Totta Program. He has been actively involved in research in both national and international projects (funded by Foundation for Science and Technology – FCT/Portugal, European Commission, and National Council for Scientific and Technological Development – CNPq/Brazil). He finished his PhD in Materials Science (2019) and Master in Chemistry (2015) with distinction from the Federal University of Rio Grande do Sul, Brazil. His PhD entitled “Development and Application of Dyes and New Fluorescent Microstructured Materials for Latent Fingerprints Detection and Clinical Diagnosis” was nominated by unanimity for the Capes Award – Best PhD thesis 2019 in the materials area. During his PhD, he completed an internship at Scientific Police Laboratory/Judiciary Police in Toxicology, Ballistic and Identification department. From 2019 to 2021, as a postdoctoral research fellow at the National Laboratory of Energy and Geology (LNEG), he continued to investigate the synthesis of the new luminescent molecules, namely, tetraphenylethene and pyrenes derivatives for photovoltaic application. His research interests include design, synthesis, computational chemistry, optical and electrochemical properties of new heterocyclic molecules and structured materials as well as their multidisciplinary application: forensic, therapeutic, clinical diagnosis, and solar cells.
