<p class="summary">Data scientist with a PhD in physics and numerical modeling. I lead battery modeling and diagnosis at Circunomics: state-of-health estimation, degradation and remaining-life modeling for EV and stationary batteries in first and second life. My research background is in inverse problems and adjoint-state methods; I combine physics-based and machine-learning models and take them from data pipelines to production.</p>
