new feature of the landscape of the AIllinois Physics Department is the Institute for Condensed Matter Theory, which was launched during the October 2007 BCS@50 Conference. This institute—ICMT—aims to foster a highly interactive, cutting edge research environment that encourages members to take on the most challenging, long-term research questions in condensed matter theory and related areas. ICMT is led by Director Paul Goldbart and Chief Scientist Tony Leggett, who are assisted by staff members Becky McDufee and Visitor Ruslan Prozorov (Iowa State University/Ames Lab) takes a Goldbart in his office, explaining his objectives for the ICMT Sue Lynn Herdle. look at remodeling plans with ICMT Director Paul M.
