From 1986 till 1994 she was the local coordinator of the national research group Geometrical Structures, Combinatorics and Applications.
She has taken part in all meetings organized in these years by the National Research Group (GNSAGA of CNR), in international meetings on combinatorics, finite geometries and applications (specially in Germany: Oberwolfach, Augsburg, München, Kiel), and also in the two-year international Italian meetings regarding Combinatorics', giving lectures about her research topics.
