General Information

The Opening Workshop for the SAMSI program on Random Media will be held on Sunday - Wednesday, September 23 - 26, 2007 at the Radisson Hotel RTP in Research Triangle Park, NC. It will be initiated on Sunday by tutorials given by Eric Vanden-Eijnden and Jack Xin.

The workshop will focus on the formulation of challenges and directions to be pursued during the Random Media program. Focus areas during the program are anticipated to include, but are not limited to, the following topics: time reversal, interface problems, imaging problems, scattering theory, heterogeneity in biological media, and porous media. One goal of the workshop is to obtain community input regarding the formation of working groups for the program and to promote engagement (via web or teleconference) of those who will not be in residence at SAMSI during the program. The workshop will engage a broadly representative segment of the mathematical, statistical and discplinary sciences.
