As noted in Derek Bok's "Higher Education in America," there is a trend in increased funding for large interdisciplinary research programs since the 1970's (Think NSF MRSEC, for example).
What is the root cause or viewpoint for a shift towards this style of funding, as compared to single-PI research grant? Additionally, if this trend continues, administrators will increasingly pressure their departments into focusing on this type of funding source. Will academia eventually approach a similar climate to a national lab (ie, large teams working on interdisciplinary projects)?
