Yves Leuzinger is an environmental engineer who, during his professional life, had the following vision: if people are not the focus of our concerns, technology is useless. As Director of the Geneva School of Engineering, Architecture and Landscape (HEPIA), from 2009 to 2021, Yves Leuzinger’s approach was therefore above all organisational and managerial. He thus gave meaning to the whole training process so that future engineers may be pillars of a “sustainable development generation”.
