Born in Chiavari in the province of Genoa in 1968, Marcello is not a mountain professional. A professor of operations research at the University of Genoa, he considers himself a “high-altitude sailor” – he doesn’t live in the mountains but on the Ligurian coast, overlooking the sea. He experiences the mountains in every season and in every way: from classic to modern routes, from big-wall aid climbing to trad free climbing, from mixed climbing to ice climbing and ski mountaineering, from steep skiing to downhill ski racing, to expeditions in large mountain ranges outside Europe. He loves to call himself a “vagabond of the vertical.” His profession and his mountaineering share an element that is essential for him: freedom. Freedom to choose topics and research methods in the first case, and freedom to choose what wall to climb, what route to follow and what style to use in the second. Even before becoming a mountain lover he was an incurable freedom lover. He is an academic of the Club Alpino Italiano.
