A short introduction

Get in touch

I am a machine learning engineer and computational scientist with a PhD in Physics and over ten years of international R&D experience in Brazil, the United States and Singapore. At Ilum – School of Science, CNPEM, I work at the intersection of AI for Science and electronic structure.

My work combines Fourier neural operators and symbolic regression for electronic densities with graph neural networks and machine-learning interatomic potentials for atomistic simulation. I build data and ML pipelines in Python and PyTorch, using high-performance computing to scale training and simulation workflows.

I develop open-source scientific software, including Poraquê, Mandacaru and Quasigraph, and build applications from the numerical core through the API, interface and deployment. My experience also includes leading multidisciplinary research teams and teaching physics, Python and C++ at undergraduate and graduate level.
