About Eric Fonseca

My research goal is to accelerate energy storage technologies, a journey that I've embarked on with the help of modern machine learning and quantum physics. My dissertation was a testament to this, as it focused on using machine learning to enhance physical models and train AI models with physics, surpassing their physics-driven counterparts. With over a decade of experience in creating, modeling, and characterizing materials, I've had the privilege of leading and being a part of numerous interdisciplinary research teams, each contributing to our collective understanding of energy storage technologies. These skills were tested at NASA Ames Research Center and the Molecular Magnets for Quantum Materials Energy Research Frontier Center, where we made significant strides in discovering molecules and materials for Li-ion batteries and quantum information devices. These breakthroughs are not just scientific achievements but also contribute to the global effort to reduce the effects of climate change and enhance our ability to solve more extensive and complex problems. Our work is not just theoretical; it has practical applications that can make a real difference.

    • I developed software and algorithms for materials discovery and materials characterization using an extensive toolset combining machine learning, physics, and custom software development. I am proficient in using VASP, Gaussian, Quantum Espresso, and NWChem for quantum calculations coupled with common packages such as RDKit, Pymatgen, PyIron, PySCF and more. I am proficient in using Fortran, Python, PyTorch, Tensorflow, JAX, C++, OpenACC, Linux/bash scripting, and MATLAB. • I am the lead developer of the VASPsol solvation package (https://github.com/henniggroup/VASPsol) used by thousands of researchers globally. • My work has extended the VASPsol parameterization beyond water to 19 different solvents, opening up a diverse range of applications from catalysis to studying materials for batteries. • I have developed a GPU-accelerated version of the VASPsol code using OpenACC• I have used Machine Learning and artificial intelligence to improve prediction accuracies for solvated systems. Through the use of transfer learning and active learning, I have improved intensive property prediction using molecular structures, as well as improved solvation free energy and thermodynamic activity coefficients. • We have been awarded the EAGER: SSMCDAT2023: Database generation with Dr. Megan Butala to identify trends in inter- and intrapolyhedral connectivity and energy storage behavior (DMR-2334240). Our collaboration has led to the successful implementation of artificial intelligence algorithms to predict the properties of transition metal oxide battery materials. • Member of the Molecular Magnetism for Quantum Materials (M2QM) Energy Research Frontier through the Department of Energy. I have developed methods for using artificial intelligence to discover novel spin-crossover molecules for quantum information devices.
