I am a senior exploration geologist at Petrobras, a Brazilian energy company, and a postgraduate researcher at the Institute of Applied Geoscience (IAG), School of Earth and Environment, with support from Petrobras.

Before joining the Sedimentology research group in November 2023, I earned a bachelor's degree in geology in 2008 and a master's in Regional Geology and Geophysics in 2011 from UnB (University of Brasilia).

Since 2010, I have been performing as an exploration geologist at Petrobras. I have devoted myself to being a geologist interpreter and providing technical support to decision-making processes in some basins that lie offshore in the Brazilian Equatorial Margin (BEM).

I have extensive experience using subsurface data, including 3D seismic, cores logs, petrophysical and biostratigraphy data to do seismic interpretation, petrophysical analysis, 3D geological modelling, and geological uncertainty analysis.

This approach has been applied in many contexts, including regional geological interpretation for petroleum systems, identifying new prospects in the Brazilian Equatorial Margin, risk assessment and volumetric analysis, appraisal plans, and portfolio management.

Research interests

My research focuses on the tectono-stratigraphic evolution of depocentres controlled by rifts oblique to transform margins, specifically in the Barreirinhas Basin (BB), the central portion of the BEM.

My experience in the industry has revealed the necessity of understanding the complex relationship between these environments of oblique tectonic and their different deposystems. As a postgraduate researcher, my interest is analysing tectonic and stratigraphic evolution through sedimentary patterns from rift depocentres and their evolution to the drifting stage. In this way, to understand how accommodation is influenced by the implementation to transform margin in oblique tectonic settings, highlighting the geological controls that impact the architecture of turbiditic deposits.

The database for this project comprises a regional 3D seismic reflection survey acquired in 2016, 3D-Megabar, which covers an area of 14,000 km2, and, adding to the seismic data, a well database comprising 20 wells was integrated.

The topics of my interest as a postgraduate researcher are:

  • Brazilian Equatorial Margin.
  • Deep marine basins.
  • Accommodation and deposystems.
  • Geological controls on depositional architecture.
  • Turbidites and siliciclastic reservoirs.


  • MSc in Regional Geology and Geophysics, UNB (University of Brasilia).
  • BSc Geological Sciences, UNB (University of Brasilia).
