BTW, it’s difficult to say that ARWU has a Pacific Rim bias when UCLA, UCSD, UCF, UDub, and Stanford make up 5 of the top 9 universities by research grants in the country. Cal isn’t up there because it doesn’t have a med school, but its research expenditures are about the same as UMich research expenditures:
