Renato da Silva Carreira is an Associate Professor (Level 2) in the Department of Chemistry at PUC-Rio since 2011. He holds a BSc in Oceanography (1990) from UERJ and an MSc (1994) and PhD (2000) in Chemistry from PUC-Rio, with a senior postdoctoral stay at the Alfred Wegener Institute for Polar and Marine Research (2017). He was a faculty member at UERJ (1996–2011), coordinating its Graduate Program in Oceanography (2007–2010). At PUC-Rio, he coordinated the Graduate Program in Chemistry (2013–2016) and headed the Department of Chemistry (2023–2026); he has led the Laboratory of Marine and Environmental Studies (LabMAM) since 2016. His research covers three lines: (i) molecular and isotopic proxies for the sources, transport and fate of marine organic matter; (ii) chemical pollution of the oceans by oil and sewage, including impacts on marine biodiversity; and (iii) analytical methods for persistent organic pollutants and contaminants of emerging concern, applied to chemical exposure assessment within a One Health approach to the ocean. He has supervised 9 doctoral theses, 20 master's dissertations, 8 postdoctoral researchers and 30 undergraduate projects, and currently supervises 4 students and researchers. He has published 108 indexed articles and 11 book chapters, edited 1 book, and worked with some 150 co-authors in Brazil and abroad.
