Tasso Guimarães holds a PhD and a master’s degree in Geology from the Federal University of Pará, and a degree in Oceanography from the same university.

As a researcher at ITV DS since 2012, he has worked on fluvial-lacustrine stratigraphy, environmental geochemistry, applied palynology, and social perception of hydrological risks. He studies ecological transitions, critical species, and vulnerable communities, with a focus on Amazonian territories impacted by mining. Guimarães uses transdisciplinary and multiproxy approaches to socio-environmental diagnostics and sustainable planning.

He is an editor and reviewer for international journals and a professor in the Professional Master’s Degree in Sustainable Use of Natural Resources at ITV, having coordinated the program from 2019 and 2021.

Silvio Ramos holds a PhD and a master’s degree in soil science, and a degree in Agronomy. As a researcher at ITV DS, he is a professor and coordinator of the graduate program in Sustainable Use of Natural Resources at ITV DS, as well as a lecturer at the Federal Rural University of Amazonia (UFRA). He works on the propagation and growth of native species, the recovery of mined areas, bioindicators, and soil carbon stocks. He teaches subjects related to forest restoration.

Renato Silva Júnior holds a PhD in Environmental Sciences, a master’s degree in Geology and Geochemistry, and is a geologist who graduated from the Geosciences Institute of the Federal University of Pará (UFPA).

Since 2012, he has worked as an adjunct researcher at ITV DS, coordinating the monitoring of the Itacaiúnas River Basin. He is also a permanent professor in the Professional Master’s Degree in Sustainable Use of Natural Resources in Tropical Regions, dedicating himself to teaching, research, and academic supervision.

With over 20 years of experience in Environment and Water Resources, he has worked at the Ministry of the Environment’s Water Resources Secretariat, contributing to pilot projects, technical support, and working groups within the National Water Resources Council.

He has taught at various institutions, including UFPA, the University of Brasília (UnB), and the University Center of Brasília (UniCEUB). He also worked for eight years at Golder Associates Brazil in the environmental and mining sectors.

Marcio Silva holds a PhD in Environmental Sciences from the Federal University of Pará (UFPA), a master’s degree in Geology and Geochemistry, and a bachelor’s degree in Geology, along with a specialization in Geology and Marine Geophysics. He works in the fields of geology, marine geophysics, coastal geomorphology, oceanography, and hydrology, with an emphasis on morphodynamics, hydrodynamics, and environmental impacts assessments and diagnostics.

He has been working as an assistant researcher at ITV DS since 2016, focusing on bathymetric surveys, hydrodynamic measurements, and environmental analysis.
Previously, he was a researcher at the Institute of Scientific and Technological Research of the State of Amapá, where he coordinated programs on coastal management and aquatic ecosystems dynamics. He also has teaching experience at various universities, delivering courses in Geology, Hydrology, Remote Sensing, and Environmental Management.

Gabriel Salomão holds a PhD in Mineralogy and Geochemistry from the Federal University of Pará (UFPA), a master’s degree in the same field, and a bachelor’s degree in Geology, also from UFPA, including an academic exchange at the University of Adelaide, Australia.

He has been an adjunct researcher at the Vale Institute of Technology Sustainable Development (ITV DS) since 2021, coordinating the Geochemical Background of the Iron Quadrangle project.

He has experience in environmental geochemistry, geochemical mapping and background studies, geochemical prospecting, applied statistics, geoprocessing, and remote sensing. Salomão was a research fellow at ITV and participated in international cooperation with the UNESCO International Center on Global-Scale Geochemistry in China. He worked as a trainee at the Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia, where he conducted research using portable spectroscopic techniques on drones. He has also carried out laboratory activities in U-Pb geochronology (LA-ICP-MS) with the TRaX group.
