Click any field hub above to unfold its leading schools and research signals.

Faculty counts are approximate (cached). Keywords are field-level high-frequency research terms with occasional cross-field noise. Field links = real cross-appointment co-occurrence (professors spanning two fields); where there's no signal it falls back to disciplinary adjacency. Signal bars (English pubs / funding / H-index / KAKEN) are offline aggregates over nationwide faculty. Data is an offline snapshot, no live queries.
