Schedule of Events
Each talk
is scheduled for 20 minutes, with 10 minutes for
questions and a break.
The official session schedule with abstracts is
here and appears below in compact form.
All talks will be in the Room 215 of the Thomas Building which is on Pollock Road, at the junction with Mifflin Road: on this Campus Map in PDF (1.4MB) it's the green building labeled TMS in grid location C5.
We have made a group reservation at India Pavilion for 7pm on Saturday night for those who are interested. We will pass around a sign-up sheet during the Saturday morning session. Guests are very welcome.
