Industrial AI and digital twins for manufacturing, built on physics-informed machine learning.

Academic

My research sits where physics meets industrial machine learning: models that learn from plant data without ignoring the process that produced it. It started in physics, with cosmology and X-ray imaging, and now focuses on physics-informed models for heavy industry.

Master's thesis

  1. 2023 — 2026

    M.Sc. in Computer Science (professional) · PPGI, UTFPR

    Thesis on physics-informed machine learning for the basic oxygen furnace (BOF) in steelmaking, advised by Prof. Dr. Silvio Sanches. Final version submitted in August 2026; the defense is being scheduled.

Papers

  1. Sep 2026

    Impact of Applying Artificial Intelligence Techniques in Risk-Based Inspection for Equipment in Oil Refining Units · ROG.e 2026, Rio de Janeiro

    Full paper, approved in four review rounds and presented in a technical session on September 24; I am a co-author and the presenter. It keeps the API 580/581 risk-based inspection of static equipment up to date from process, inspection and laboratory data, with NLP on inspection reports, tree ensembles and recurrent networks, piloted on the overhead system of a crude distillation unit. Validated by the UTFPR graduate program toward the M.Sc.
