10:45 am: Split into two discussion groups
A: solid/liquid interfaces (Dorn Room)
B: grain boundaries (remain in room)

Purpose of Discussion:
1) Summarize progress to date
2) Write Brief Report on Progress for each Group
3) Provide website links
4) Discuss future plans, directions

12:30: Lunch: together

Afternoon:

1:45: Report from Solidification group
2:15: Report from Grain growth group

~3:30pm: Where do we go from here?
o What are our accomplishments?
o Are we succeeding in what we said we would do?
o Can we/should we establish significant new directions for each subgroup?
o Is the whole greater than the sum of the parts?
o Do we want to continue for a second year, i.e. request additional funds?
o Should we meet at the major meetings (MRS, APS, TMS) instead in order to compensate for the travel budget problems at the national labs?

5:00 Adjourn

Information about Rooms and Locations:

1st Day: The workshop will take place in room 2G in Norris on the 11 and 12th of April from 8:30 - 5. There will be a laptop projector available on the first day, but not on the second. On the second day the Dorn room, 1119 in the Materials Building, is also reserved for our use from 8:30-5.

Continental breakfast will be available in the room (2G) in Norris on both days. Norris is the student center building. The "Materials Building" is called MLSB (Materials and Life Sciences Building).
