Marcos Lopes Dias graduated in Chemical Engineering from the Universidade Federal do Rio de Janeiro (UFRJ) in 1983 and obtained his Ph.D. in Polymer Science and Technology from UFRJ in 1990. He completed postdoctoral studies at the Politecnico di Milano, Italy, in 1992. He is currently a Full Professor at UFRJ and Deputy Coordinator of the Lato Sensu Postgraduate Course in Plastics and Rubber Processing. He is a CNPq Research Fellow and was recognized as Scientist of Rio de Janeiro by FAPERJ (2003–2007; 2015–present). His research focuses on catalysis in polymerization reactions, including olefins, lactones, and cyclic carbonates using metallic catalysts such as Ziegler–Natta, metallocene, and Brookhart systems. His interests also include PET recycling, biodegradable polymers, polymeric biomaterials, nanostructured systems, nanocomposites, and bio-based vitrimer materials.
