When UCSF researchers collaborate between departments, how diverse are the collaborations? Here are the top 20 UCSF departments, ranked by the average numbers of UCSF departments their multi-departmental papers include as co-authors (from among the 39 departments whose researchers had a total of 25+ multi-departmental publications published between January 2012 and November 2013).

Details: Data is drawn from UCSF Profiles, and is based on a list of all publications listed on PubMed published between Jan 2012–Nov 2013 whose authors include groups of researchers with primary affiliations to more than one UCSF department. We counted only those publications from researchers with a listed department, and only those departments whose current associated researchers published 25+ publications in conjunction with current members of other UCSF departments between Jan 2012–Nov 2013. No attempt was made to account for the widely varying sizes and scopes of different departments, the fact that researchers may have multiple departmental affiliations, or the fact that some publications may have been authored before the researchers were affiliated with their current primary departments at UCSF. These are the top 20 departments, out of a total of 39 that match our criteria.
