The diffusion of knowledge is a complex process facing numerous barriers, and interdisciplinary program is believed to be a key issue in translational research. There are variations through disciplines in type and degree of collaboration. The aim of this study is to understand to what extent corresponding author reflect collaboration degree in interdisciplinarity. As an example, we undertook the analysis of the collaboration between bioinformatics and cancer research. We categorized each authors’ profession in two groups, “Computer Scientists” and “Health Scientists”, and analysed the sample through bibliometrics and descriptive statistics based on the authors' profession. The analyses of each groups’ publications set were complemented by co-word and reference analysis. Our results show that there is no equal representation of disciplines: authorship responsibilities’ sharing is in favour of “Health Scientists“, with specificities according to countries and choice of journals.
