Campus de Beaulieu 263 Av. Général Leclerc

Rennes, France

I specialize in researching the reliability of parallel architectures, efficient hardening techniques, and mitigating radiation-induced effects. I started my academic journey with a Bachelor’s in Computer Science from the Western Paraná State University. I then pursued a Master’s and Ph.D. from the Federal University of Rio Grande do Sul in Brazil. After completing my Ph.D., I moved to Rennes, France, to work as a postdoctoral researcher in the MSCA-BIENVENÜE Postdoctoral Program in the INRIA TARAN team. Throughout my academic career, I have focused on understanding the impact of radiation on devices used in large-scale HPC centers and safety-critical applications.

Currently, I’m a researcher at INRIA Rennes in the Taran Group, where I explore the fault tolerance and reliability aspects of RISCV and Deep Neural Networks accelerators. This exciting work allows me to contribute to advancing these emerging technologies and their applications across various domains. I am eager to share my journey, insights, ongoing projects, and research publications with you through this personal website. Stay tuned for updates and collaborations as we collectively push the boundaries of knowledge in computer science, shaping more reliable and efficient computing systems.
