Senior Research Scientist — Geomagnetism
I develop and validate geomagnetic field models and related data products, with a focus on reference models and uncertainty quantification for navigation and geophysical applications. Research Scientist at CIRES, University of Colorado Boulder.
Development and evaluation of reference field models — World Magnetic Model (WMM), International Geomagnetic Reference Field (IGRF), and High Definition Geomagnetic Model (HDGM) — with attention to systematic errors and uncertainty quantification.
Learn MoreEmpirical and statistical approaches to real-time and retrospective estimation of geomagnetic disturbance indices (Dst) and cloud-based disturbance-field corrections.
Learn MoreApplication of machine learning methods to geomagnetic time series and index forecasting. Organized the MagNet data-science challenge (622 participants) to advance reproducible Dst prediction methods.
View ChallengeCollection and quality assessment of geomagnetic data from smartphone sensors (CrowdMag) and identification of magnetic anomalies associated with subsurface features such as orphaned wells (MagMapper).
Estimation of prompt-penetration electric fields from solar-wind drivers using empirical transfer functions, with applications to equatorial ionospheric variability.
View ModelAnalysis of magnetic anomalies for navigation and positioning (MagNav), including estimation of model and map error metrics and their limitations.
