Shirley Wu has followed up on her original proposal to submit a session proposal for PSB. She asks a series of important questions about going forward on this and I thought I would reply to these here to widen exposure. I think it is worth going for a session and I am happy to lead the application but there may well be better people; Jean-Claude, Antony Williams, Peter Murray-Rust, Egon Willighagen to get to lead it depending on focus.
