Summary
👤
Senior🎓
Top SchoolSheila Sagear is an Astrophysics PhD and data scientist with nine years of experience applying Bayesian hierarchical modeling and machine learning to exoplanet and stellar-kinematics problems. As a Graduate Research Assistant at the University of Florida she led development of the open-source photoeccentric Python package and used Kepler time-series data to constrain exoplanet orbital eccentricities, work published in PNAS. She also spent time as a predoctoral fellow at the Flatiron Institute where she created the zoomies package to infer kinematic stellar ages from Gaia data, demonstrating a knack for translating complex statistical methods into user-friendly tools. Her background spans high-energy ML at CERN and software contributions to NASA Ames projects, blending rigorous research with production-ready code. Based in Gainesville, she brings both deep domain expertise in astrophysics and practical software craftsmanship to interdisciplinary data challenges.
