Mostly I've been too busy doing the research (and hacking out the technical articles necessary for the job hunt) to write up much intelligible about it. But one of these days, I will.
For now, here is a little page full of audio files that I made for a broadcast by Westdeutscher Rundfunk.
I've also hacked the introduction of my thesis into net-legible form. (The rest of it has been published as articles 1 to 4 and 6 on my publication list.)
