[1] From 1981 to 1986 Ceruti worked at the University of Geneva, Faculty of Psychology and Educational Sciences, and at the Genetic Epistemology International Centre founded by Jean Piaget.

Within this framework, Ceruti developed a research program in Evolutionary Epistemology that draws on contemporary theories of biological evolution, history of ideas and genetic psychology.

Starting from the 80s, Ceruti had been collaborating with Alberto Munari and Donata Fabbri at the Cultural Psychology Center of Geneva, Ilya Prigogine at Université Libre of Brussels, Henri Atlan and Francisco Varela at CREA (Research Center in Applied Epistemology, Paris), Jean-Louis Le Moigne at the MCX (Modelisation of Complexity) Program, and Ervin Laszlo and GERG (General Evolution Research Group, San Diego).

They included, besides the already mentioned pioneers of these domains of inquiry, also Jerome Bruner, Heinz von Foerster, Ernst von Glasersfeld, Susan Oyama, Isabelle Stengers, William Thompson, Lynn Margulis, James Lovelock, Stephen J. Gould, Niles Eldredge, Brian Goodwin, Evan Thompson, Giulio Giorello, Paul Feyerabend, Paul Watzlawick, and René Thom, among others.

Between the 80s and the 90s Ceruti founded and directed three scientific journals dedicated to the development of "Complex Thinking": La Casa di Dedalo, Oikos and Pluriverso.
