A sample, not a catalogue. Most of this work happens behind closed doors: regulators' offices, boardrooms, private executive sessions, none of which publish a programme or a speaker list. Those engagements leave no public trace, by design.

What follows is the visible fraction, listed because it can be checked. Each entry links to the organiser's own record, or to the talk itself. The few private engagements named here carry the year alone, and rest on Nell's word rather than on an agenda anyone can look up.
