Solar Cycle
Long-term variability of solar magnetism and global field evolution.

I study the long-term evolution of solar magnetism across multiple cycles, focusing on cycle-to-cycle variability, global field diagnostics, and historical reconstructions that connect observations and modeling for space-weather relevant insights.

Solar Cycle Periodicity

This includes historical reconstruction, polar-field diagnostics, and links between surface magnetism and predictive space-weather indicators.

Typical questions

  • How do cycles differ in amplitude and timing?
  • What do polar fields tell us about the next cycle?
  • How far back can reconstructions be trusted?

SFT / AFT Modeling

I use surface flux transport frameworks—including AFT in data-assimilation mode—to evolve photospheric magnetic fields under realistic surface flows. This supports consistent full-Sun maps, validation against synoptic products, and sensitivity studies.

Workflow focus

  • Assimilation-ready active region inputs
  • Validation against synoptic and full-Sun products
  • Sensitivity testing under realistic flow choices

Why it matters

These models connect observations and prediction by turning surface magnetism into interpretable evolution scenarios rather than static snapshots.

Magnetic Reconnection

I investigate magnetic reconnection as a key mechanism for rapid energy release in the solar atmosphere, combining observational signatures and magnetic context to interpret transient events and connectivity changes.

Interpretive lens

  • Transient events in magnetic context
  • Connectivity changes across complex regions
  • Links between topology and energy release

Current role in site

This topic is part of the research map now, with room for a later standalone project page.

Spectro-Polarimetry

I work with polarized spectral diagnostics to infer magnetic and thermodynamic properties of solar plasma, emphasizing robust inversions, careful uncertainty handling, and consistent interpretation across instruments and observing conditions.

Method priorities

  • Careful inversions and uncertainty handling
  • Cross-instrument interpretability
  • Magnetic diagnostics tied back to physical context

How it fits

It complements the larger magnetic-field story by connecting detailed diagnostics to global evolution.

Machine Learning

I develop ML-ready datasets and models for tasks like geometry-aware cross-calibration, systematic error characterization, and feature detection/tracking—aiming for reproducible evaluation and physically meaningful outputs.

Applied directions

  • Cross-calibration for heterogeneous observations
  • Feature detection and tracking
  • Forecast-friendly data products

Design principle

The goal is not ML for its own sake, but ML that stays physically interpretable and reusable.

Tool Development

I build reusable tools for data retrieval, archiving, conversion, and analysis—designed for large solar datasets. This includes automated updates, metadata-preserving storage, and visualization/diagnostic utilities that support end-to-end pipelines.

Tooling emphasis

  • Automated updates and archiving
  • Metadata-preserving conversion
  • Visualization and diagnostic utilities
