Barros earned his degree in Applied Chemistry from Nova University of Lisbon, Portugal, in 2012. Upon graduation, he received an academic merit prize and an international exchange grant through the Luso-Brazilian Santander Totta Program, which enabled him to study in Brazil. He completed his Master’s in Chemistry in 2015 and his PhD in Materials Science in 2019, graduating with distinction from the Federal University of Rio Grande do Sul, Brazil. His doctoral research, titled "Development and Application of Dyes and New Fluorescent Microstructured Materials for Latent Fingerprints Detection and Clinical Diagnosis," was unanimously nominated for the National Capes Award - Best Thesis 2019 in the materials category. During his PhD, Barros also undertook an internship at the Scientific Police Laboratory/Portugal. Barros began his independent scientific career as a postdoctoral researcher at the National Laboratory of Energy and Geology (Portugal) where he worked for 18 months (2019–2021). He later served as a postdoctoral researcher at the Faculty of Pharmacy, University of Lisbon, for 12 months (2021–2022), before taking on his current role as a postdoctoral researcher at Instituto Superior Técnico, University of Lisbon (2023–present), one of Europe’s top 17 higher education institutions in engineering. Barros has received two research grants from the Brazilian National Council for Scientific and Technological Development - CNPq (190429/2012-7 and 153914/2016-5) and has been actively involved in several projects in Portugal as Principal Investigator (PI) and postdoctoral researcher. His notable projects include IDEAS (Novel Building Integration Designs for Increased Efficiencies in Advanced Climatically Tunable Renewable Energy Systems), funded by the European Union's Horizon 2020 program (grant 815271, €4 million); Drug Discovery for p53 PPI-Targets (PTDC/QUI-QOR/29664/2017, €234,000); and URE-LOCKERS (as PI) - Urease Next-Generation Inhibition Therapy (PTDC/MED-QUI/3542/2020, €243,000), funded by FCT Portugal. Barros has demonstrated expertise in managing funded projects as a PI and has collaborated with researchers from Tunisia, Portugal, Brazil, Cape Verde, Colombia, and Ireland. In teaching, he contributed to two undergraduate courses at the Federal University of Rio Grande do Sul, Brazil, and an online master’s course at the University of Cape Verde. He has supervised six undergraduate and master’s students and served as an evaluator for students' final course defenses. Additionally, Barros serves as a reviewer for scientific journals such as ELSEVIER's Journal of Photochemistry and Photobiology A and Forensic Chemistry, MDPI's Materials and Crystals, Springer's Analytical Science and Emergent Materials, and the Royal Society of Chemistry’s RSC Advances. He has presented his work at numerous national and international scientific conferences. Barros's research is application-driven, prioritizing cost-effectiveness, rapid readout, and sustainability. He has published 20 papers in high-impact international peer-reviewed journals, 11 as first author, in the last 9 years. Currently, at Instituto Superior Técnico (Sustainable Nanochemistry Group), he is developing alternatives to conventional antibiotics, with a focus on specially designed polyurea dendrimers for biomedical applications. His research encompasses the design, synthesis, and characterization of heterocyclic molecules and biomaterials for applications in forensics, therapeutics, and solar cells. It aligns with the principles of sustainability, green chemistry, and engineering. Between May 2022 and April 2023, Barros was unemployed due to the conclusion of his previous employment contract, which temporarily affected his laboratory-based scientific productivity. During this period, he enhanced his language skills and taught Portuguese to students from over 30 nationalities through the Preply platform, maintaining an active role in education and communication.
