I study how the Sun's magnetic field changes from one solar cycle to the next and how that drives space weather at Earth, using a century of observations, flux transport models and machine learning.

Observation: Solar Cycle Variability
Why each 11-year cycle is different: long-baseline evolution, polar field reversals and cycle-to-cycle structure from a century of data.
Project 2
Modeling: Solar Cycle Variability
Surface and advective flux transport (SFT and AFT) models that evolve the Sun's magnetic field, with data assimilation and forecasts.
Project 3
Observation: Feature Identification and Tracking
Calibration, detection, tracking and forecasting products built for reuse, from historical plates to modern magnetograms.
