Applications are now being accepted for fellowships at the National Center for Supercomputing Applications (NCSA). Proposals are sought from faculty at the University of Illinois at Urbana-Champaign and at institutions around the country for cross-disciplinary collaborations with NCSA staff. The fellowships aim to combine researchers' discipline-specific knowledge with NCSA's R&D expertise to contribute to the creation of the national cyberinfrastructure. University of Illinois faculty and staff are eligible for the NCSA/UIUC Faculty Fellows Program. NCSA expects to award about a dozen of these fellowships. Deadline for submissions is March 30, 2007. Summer Faculty Fellowships are available to faculty at U.S. institutions other than the University of Illinois at Urbana-Champaign. NCSA expects to award about six of these fellowships. Deadline for submissions is March 16, 2007. Please contact fellowship coordinator Radha Nandkumar with proposal ideas at fellowships@ncsa.uiuc.edu or (217) 244-0650. Proposed collaborations must be discussed with and endorsed by NCSA staff before applications are submitted.
