Presentation at the Fourth Annual ECAR/HP Summer Symposium for Higher Education IT Executives, July 13-15, 2005, New Castle Island, New Hampshire. Scientific and engineering research increasingly involves collaboration across multiple organizations. Technological advances have made such cross-boundary projects possible, yet they can carry high coordination costs. This talk discusses coordination mechanisms that can bring researchers together (physically and virtually) to reduce the potentially negative impact of collaborations involving multiple universities.
