The growth of the Centre and its activities has led to the identification of three main Research Groups: system level policies, institutional and organisational analysis, and relationship between higher education and the environment. This Groups have been defined mostly with the purpose of facilitating the coordination and organisation of the several research projects and strengthening continuity within the research programs. Although CIPES is organised around three main Research Groups, there is an intense interaction between all researchers and all research projects. This interaction means that each Research Group significantly articulates with and is nurtured by the remaining Groups, through the sharing of processes and results of its research activity. This has contributed to stimulate a rich and innovative intellectual environment.
