Profile

Colombo Celso Gaeta Tassinari is a distinguished Brazilian geologist known for his significant contributions to isotope geology and its applications in petroleum exploration and metallogenesis. He received a degree in geology from the University of São Paulo (USP) in 1975, followed by a master’s degree in geosciences with a focus on mineralogy and petrology in 1981, and a Ph.D. in geochemistry and geotectonics in 1988, all from USP. 

Currently, Tassinari is a full professor at USP’s Institute of Energy and Environment (IEE-USP), where he also directs the Technical Laboratory for Geological Storage of CO₂ and H₂. His previous administrative roles include director of the Institute of Geosciences at USP from 2008 to 2011, and director of IEE-USP from 2015 to 2019. 

Tassinari’s research focuses primarily on isotope geology, with an emphasis on geochemical applications in petroleum exploration, metallogenesis, and regional geology. He coordinates the National Institute of Science and Technology for Analytical Techniques Applied to Petroleum and Gas Exploration in Brazil.  His work has been widely recognized, culminating in the 2023 ANP Award for Technological Innovation as Academic Personality of the Year in the Oil, Gas and Biofuels Sector. 

An active member of the scientific community, Tassinari is a member of the Brazilian Academy of Sciences, the São Paulo Academy of Sciences, and the Academy of Sciences of Lisbon. His commitment to the advancement of the geosciences has significantly influenced both academic research and practical applications in the energy and environmental sectors.
