Guillaume PITON studied at the Institut National Polytechnique de Grenoble in the former School of Hydraulics and Mechanics, now called ENS de l'Energie de l'Eau et de l'Environnement (ENSE³). He then worked as a hydraulic engineer from 2009 to 2013 at ARTELIA (formerly SOGREAH), on the Grenoble and Chambéry sites. He has carried out multiple water study and development missions: hydrology, hydraulic modelling, design of flood protection and river rehabilitation works, site preparation and execution control, impact study and regulatory file. In 2013 he joined the IRSTEA (ex-CEMAGREF) to carry out a doctoral thesis on the control of solid transport of torrents by torrential correction works and deposition ranges. This work has made it possible to combine experimental approaches with field analyses and historical research. Since his defence in 2016, he still works on mountain hydraulics and risk protection. He is now permanent researcher in the ETNA research unit of INRAE (merger of IRSTEA and INRA).
