The article is a bibliometric study on the scientific collaboration networks between professors in the Graduate Program in Epidemiology from the Federal University of Pelotas (PPGE/UFPel). The characteristics of the collaboration were studied by means of co-authorship of articles published in journals between 1991 and 2002. The analysis showed that professors publish more shared than single authorship articles. Correlation between productivity and collaboration was not found, since productivity rate and authorship rate per paper did not exhibit the same trend, i.e., the number of published papers increased whereas the number of collaborators was maintained. The analysis of social networks revealed a configuration around the most productive professors.
