D'origine française, Cécile Münch-Alligné est née en 1979 à Strasbourg. Elle est ingénieur en hydraulique et mécanique, diplômée de l'Ecole Nationale Supérieure d'Hydraulique et Mécanique de Grenoble de l'INPG, promotion 2002. Elle a obtenu son doctorat en mécanique des fluides et transfert de l'INPG en 2005 après avoir réalisé une thèse sur la simulation numérique des grandes échelles de la turbulence. Elle a ensuite passé quatre années à l'EPFL au Laboratoire de Machines Hydrauliques en tant que collaboratrice scientifique pour développer les activités du laboratoire dans le domaine de la simulation numérique des écoulements dans les turbomachines. Depuis septembre 2010, elle est professeure à la HES-SO Valais-Wallis en énergie hydraulique. Elle a mis en place un groupe de recherche dans ce domaine qui est actif dans de nombreux projets cantonaux, nationaux et internationaux. Elle coordonne le groupe Hydroélectricité membre actif des centres de compétence pour la recherche énergétique en Suisse (SCCER) pour l’approvisionnement en électricité (SCCER-SoE) ainsi que pour les réseaux et leurs composants (SCCER-FURIES). Elle est membre du board du SCCER-SoE et de la Commission fédérale pour la recherche énergétique (CORE).

SCCER-FURIES
"Swiss Competence Center for Energy Research – Future Swiss Electrical Infrastructures" joins the competences of the top Swiss academic and industrial actors in the area of power / energy systems granted by CTI. HES-SO Valais-Wallis will contribute to the task “Control of massive DG and distributed storage” of WP1 "Regional multi energy grids". In particular, this contribution will be focused on the development of concurrent hydraulic, mechanical and electrical engineering of small units featuring fast dynamics and low CAPEX.

DUO TURBO
"Providing Industrial and Competitive Family of Low-CAPEX Integrated Plug-and-Play Energy Recovery Stations” is a 3 years project funded by KTI involving HES-SO Valais-Wallis, EPFL and three industrial partners. The project focuses on turning a counter rotating micro-turbine proof of concept into a range of standard energy recovery stations able to harvest energy on drinking water networks. (1 Million for 3 years)

Hydro VS
"Valorisation de la production d'énergie des infrastructures hydrauliques existantes” is a 5 years project supported by The Ark Energy initiative funded by the Ark Foundation (VS) evolving EPFL and HES-SO Valais-Wallis. In this project, HES-SO Valais-Wallis is in charge of the development of an iso-kinetic turbine for river and involved in the development of a micro-counter-rotating turbine in a close collaboration with EPFL.
> Leader of the HES-SO Valais-Wallis WP’s

Arbaz
"Station de transfert d'énergie par pompage et turbinage à Arbaz : étude de l’installation, de l'intégration et de la gestion optimale du réseau" is a 1 year project supported by The Ark Foundation involving EPFL, CREM, Cimark and HES-SO Valais-Wallis. In this project, the HES-SO Valais-Wallis is studying the feasibility of a micro pumped storage power plant.
> Leader of the project

Clean City
This 2-years project is supported by the HES-SO and involved HES-SO Genève, HES-SO Fribourg and HES-SO Valais-Wallis. The HES-SO Valais-Wallis is in charge of flow numerical simulations of pollutant dispersion around a cubic building using a opensource code OpenFOAM.
