PVC's Lunchtime Seminars

I'm preparing for the new round of PVC's Lunchtime Seminars today. The first will be led by Dr Charlotte Sleigh in History, who will gather together a group of fellow academics from across the University to look at the question of 'the Face of the Expert'. Who are (and were) experts? How do they get to be experts? Can they cease to be experts? What are their relationships with lay persons? How do these relationships structure knowledge and society? And as members of academia are we experts or not?
It should be interesting: Charlotte's idea is that, rather than have each participant give individual talks about their research (which we've done in the past), they will discuss issues raised by the topic, similar to Radio 4's 'In Our Time.'
All welcome: it starts at 12:30 in Keynes Seminar Room 14.
