Talks, videos and slides

Research presentations

Slides, lecture series, seminar talks and videos, from technical talks to public explanations.

This page is intentionally more visual than a paper list. Talks are often the quickest way to see the idea before fighting the notation.

For laypersons. A good talk is the trailer, not the movie. It should show why the problem matters, what the pictures mean, and where the proof is hiding.
