I came to Valencia on a (exceptionally) cold winter day, but could hardly care about the cold, as I was delighted with the blossoming orange trees throughout the city. When I started working in INGENIO, it became obvious that orange trees were not the only gift the city had to offer… Besides an appealing work environment, my sabbatical visit in INGENIO was enriched with a very friendly atmosphere, not to mention many stimulating discussions on networks and social innovation with colleagues, as well as truly engaging research seminars. I thank especially Jordi Molas Gallart and Pablo d’Este for their help in the process.
