Christof HolligerOriginaire d'Adliswil, Christof Holliger est né en 1959. Diplômé de l'ETHZ en biologie en 1984, il mène des travaux de recherche dans le domaine de la microbiologie environnementale à l'Université d'Agriculture de Wageningen (Pays-Bas) où il obtient son doctorat en Science de l'environnement en 1992. En 1992, il retourne en Suisse engagé comme collaborateur scientifique et chef de groupe à l'Institut Fédéral pour l'Aménagement, l'Epuration et la Protection des Eaux (EAWAG) à Kastanienbaum. Il y continue ses recherches sur la déchloruration réductrice, commencées aux Pays-Bas, et dirige des travaux sur la réduction des composés nitroaromatiques, la réduction du fer et la méthanogenèse psychrophile dans les sédiments des lacs. En octobre 1998, il est nommé professeur assistant en biotechnologie environnementale au Département de génie rural de l'EPFL. Ses recherches visent l'application des micro-organismes anaérobies pour le traitement des eaux résiduaires. En novembre 2004, il est nommé professeur associé et devient responsable du laboratoire de biotechnologie environnementale à la Faculté de l'Environnement naturel, architectural et construit. L'utilisation des techniques de la biologie moléculaire pour la caractérisation des communautés microbiennes impliquées dans le biotraitement de l'air, des eaux et des sols pollués est un outil clé dans les différents projets de recherche visants le développement des nouveaux procédés de traitement.
Johan Alexandre Philippe GaumeI started my scientific career in 2008 at the Grenoble University in the IRSTEA laboratory where I did my master's thesis on the rheology of dense granular materials using the discrete element method. In the same lab, I followed with a PhD on the numerical modeling of the release depth of extreme avalanches using a combined mechanical-statistical approach and spatial extreme statistics. In 2013 I obtained a postdoc position at the WSL Institute for Snow and Avalanche Research SLF in Davos where I was in charge of developing and applying numerical models to improve the evaluation of avalanche release conditions and thus avalanche forecasting. While my PhD was mostly theoretical and numerical, my postdoc in Davos allowed me to gain a practical expertise by participating in laboratory and field experiments which helped to validate the models I develop. In 2016, I was awarded a SNF grant to work as a research and teaching associate in CRYOS at EPFL on the multiscale modeling of snow and avalanche processes. I developed discrete approaches to model snow micro-structure deformation and failure in order to evaluate constitutive snow models to be used at a larger scale in continuum models. I also developed numerical models for wind-driven snow transport. In 2017, I was a Visiting Scholar at UCLA to work on a Material Point Method (MPM) to simulate both the initiation and propagation of snow avalanches in a unified manner. The UCLA MPM model was initially developed for the Disney movie "Frozen" and has been modified and enriched based on Critical State Soil Mechanics to model the release and flow of slab avalanches. The results of this collaboration have been published in Nature Communications. In 2018, I was awarded the SNF Eccellenza Professorial Fellowship and became professor at EPFL and head of SLAB, the Snow and Avalanche Simulation Laboratory. At SLAB, we study micro-mechanical failure and fracture propagation of porous brittle solids, with applications in snow slab avalanche release. We also simulate avalanche dynamics and flow regime transitions over complex 3D terrain through the development of new models (depth-resolved and depth-averaged) based on MPM.In 2020, I obtained a SPARK grant to develop a new approach to simulate and better understand complex process chains in gravitational mass movements, including permafrost instabilities, rock, snow and ice avalanches and transitions to debris flows.
Paolo BenettinI was born in Padova, Italy, in 1986. After high school, I started the Environmental Engineering program at the University of Padova (Bachelor and Master), where I followed the 'soil protection' curriculum. During my Master studies I spent a semester as Erasmus student at Wageningen University (Wageningen, the Netherlands) to follow courses in Hydrology. After graduation, I decided to bring my education further and I started a Ph.D. at the civil and environmental engineering department at the University of Padova. My Ph.D. thesis focused on hydrologic transport and travel time distributions at the catchment scale. My contribution to the subject included both new theoretical formulations and extensive numerical applications to real catchments. During my Ph.D., I also spent 7 months as visiting research fellow at Virginia Tech University (Blacksburg, USA). Since I arrived at EPFL as post-doc in 2015, I started being involved in field and experimental activities, which allowed me to learn about practical experimental problems. In 2017 I had the opportunity to by hired by the ECHO laboratory as a permanent scientist, conducting research in the field of catchment hydrology.
Alexandre ButtlerI am a honorary professor at Ecole Polytechnique Fédérale, Lausanne - EPFL. Up to 2019, I was a joint-professor between EPFL (Head of the laboratory of Ecological Systems - ECOS) and the Swiss Federal Research Institute WSL for Forest, Snow and Landscape (Head of the research group Pasture Woodlands and Wetlands) and head of the Site WSL-Lausanne. I was also professor at the laboratory of Chrono-Environnement (UMR CNRS 6249) of the University of Franche-Comté, Besançon (France). I am author or co-author of over 160 papers in international ISI cited peer-reviewed journals.
