Lecturer and teaching assistant for EPFL Civil Engineering section. EXPERTISE Constitutive modelling of unsaturated soils Coupled finite element modelling Rheology of unsaturated soils Heat exchanger piles / energy geostructures Landslides HONORS In 2009, two articles of which Mathieu Nuth is the co-author are ranked in the "Top 25 hottest articles" of the Journal Computers and Geotechnics, entitled 'Advances in modelling hysteretic water retention curve in deformable soils' by Nuth, M. and Laloui, L, and 'On the use of the generalised effective stress in the constitutive modelling of unsaturated soils' by Laloui, L. and Nuth, M. In 2008, the article 'Effective Stress Concept in Unsaturated Soils: Clarification and Validation of an Unified Framework', by Nuth, M. and Laloui, L. published in the International Journal for Numerical and Analytical Methods in Geomechanics is rated in the top 5 most read papers of the journal. In 2008, Mathieu Nuth is awarded the "Houpert" prize of the French Society for University Civil Engineering during the young researchers competition. In 2006, Mathieu Nuth is awarded the "Best poster award of ENAC PhD poster exhibition 2006" delivered by EPFL-ENAC school. BIOGRAPHY Born in France in 1981, and of French-Cambodian origin, Mathieu Nuth is trained in "Ecole Centrale Nantes" engineering school within the civil engineering section. He perfoms his master thesis in 2004, entitled "Thermal ground improvement: application to heat exchanger piles" in the Soil Mechanics Laboratory (LMS) in EPFL. He defends in 2009 his PhD thesis entitled "Constitutive modelling of unsaturated soils with hydro-geomechanical couplings" under the supervision of Professor Lyesse Laloui in the same laboratory. He is now researcher in LMS on the issue of the coupled behaviour of soils. Mathieu Nuth is the author of a thesis, 8 journal articles, 9 conference papers and a book chapter. He possesses the "First Certificate in English" and the "Diploma Basico de Español". MAIN PUBLICATIONS H. Péron, S. Salager, M. Nuth, P. Marschall, and L. Laloui.
