International Workshop on “Advances in Laboratory Testing and Modelling of Soils and Shales” will take place in Swiss Alps, 18-20 January 2017. This International Workshop is a 2.5-day event promoting the exchange of ideas, practices and state of the art about laboratory testing and modelling of soils and shales. It aims at bringing together researchers working on soils and shales, in order to stimulate the debate around recent advances in laboratory testing and modelling of these geomaterials. Attached is the call for abstracts, and further details on the Workshop are available on the website: http://atmss.epfl.ch
