It's weird to see David Chalmers with short hair. For as long as I have been aware of him, he has had long hair that made him look like a member of Whitesnake's reunion tour, not a world renowned philosopher.
Be that as it may, in this TED Talk from TED2014, Chalmers talks about the subject for which he is best known, consciousness.
