This work verifies whether research diversification by a scientist is in some
measure related to their collaboration with multidisciplinary teams. The
analysis considers the publications achieved by 5300 Italian academics in the
sciences over the period 2004-2008. The findings show that a scientist's
outputs resulting from research diversification are more often than not the
result of collaborations with multidisciplinary teams. The effect becomes more
pronounced with larger and particularly with more diversified teams. This
phenomenon is observed both at the overall level and for the disciplinary
macro-areas
