I'll be taking a leave of absence from Stanford during the winter quarter of 2013 (all of February and March) to work with (and learn a lot from) the Shell Centre in Nottingham. While I'm in town, I'd love to do some work with UK maths teachers — workshops or lectures or whatever else. I have four openings. If I can help out, please drop me a note at firstname.lastname@example.org.
2012 May 18: Apologies for the double-post. I just finished up some renovations around here.
