I am a dedicated researcher passionate about the entire scientific process, from the initial planning of a project and the meticulous execution of fieldwork and analysis, to the final dissemination of results.

My research focuses on understanding the fundamental processes that build and collapse mountain ranges and that localize strain into shear zones. I am currently involved with EPOS-NG, where I am expanding my field of expertise to bridge the gap between Structural Geology, Tectonics, and Geological Mapping with Geohazards. The goal of this work is to translate fundamental geological knowledge into applied science for a more resilient Norway.

To investigate these processes, I integrate extensive fieldwork, including geological mapping and structural data collection, with a suite of advanced analytical techniques.

My expertise spans:

• Digital Geological Mapping & Fieldwork: ArcGIS, QGIS, FieldMove Clino, GIS KIT, Google Earth, GeoMapApp, and Remote Sensing.
• Microfabric Analysis: Applying Electron Backscatter Diffraction (EBSD) and Transmission Electron Microscopy (TEM) to understand deformation mechanisms.
• Geothermometry: Using geothermometers like Titanium-in-quartz, Titanium-in-zircon, and Zr-in-rutile to constrain temperature conditions during deformation.
• Anisotropy of Magnetic Susceptibility (AMS): To analyze rock fabric and strain.

I apply these methods to study deformation across a range of tectonic settings, with a particular interest in hot orogens like the Pan-African-Brazilian system and cold orogens like the Caledonides.

In addition to my research, I am passionate about knowledge sharing and find teaching to be a central and rewarding part of my work. I have broad experience from various academic environments, from Brazil to Norway, and have taught a wide range of courses at the bachelor's, master's, and PhD levels. This cross-cultural experience has strengthened my ability to adapt my teaching to reach students from diverse backgrounds.

Submitted projects:

I have developed a proposal for a new Center of Excellence (SFF) submitted by the University Museum to the Research Council of Norway in November 2025 (Application ES756388 / Project 362229): The Center for Integrated Earth–Society Dynamics (ESD). This initiative, which I have co-proposed, seeks to pioneer a new science of human-environment interaction by integrating geoscience, biology, archaeology, and anthropology. Our mission is to trace the geological foundations of modern society back 500 million years, decode the co-evolution of natural and societal systems over the past 10,000 years, and translate this deep-time understanding into actionable future scenarios. Status: Under evaluation.

I was deeply involved in developing the proposal for the groundbreaking Norwegian Research School on Natural Hazards (NatHaz). Submitted by our Geoscience Institute to the Research Council of Norway (Application ES751877 / Project 360154) in June 2025, this Coordination and Support Activity was a collaboration with Høgskulen på Vestlandet, the University of Oslo, the University of Tromsø, the University Centre in Svalbard (UNIS), and the NTNU Faculty of Engineering. The school was designed to be a leading national initiative, strengthening Norway's capacity to address natural hazard challenges by training a new generation of highly skilled PhD candidates. Status: Not granted.
