The lecture will remain online so that those unable to attend at this time will be able to do it later. As usual, the attendees will be able to ask questions to the lecturer by e-mail during the subsequent 48 hours.

Jean Sulem is Professor at Ecole des Ponts ParisTech, and Research Director. He leads the Geotechnical Group CERMES at the Navier Laboratoire. His research interests are related to Bifurcation Theory applied to stability and strain localisation analyses, Constitutive Modelling of Geomaterials, Experimental Rock Mechanics, Thermo-Hydro-Mechanical Behaviour of Geomaterials with applications to Tunnelling, Petroleum Engineering, Deep Geological Storage and Fault Mechanics.

He has published two books "Bifurcation Analysis in Geomechanics" with Ioannis Vardoulakis, in 1995; and "Meso-scale Shear Physics in Earthquake and Landslide Mechanics" with Yossef Hatzor and Ioannis Vardoulakis in 2009. He is the author of more than 75 papers in peer-reviewed journals.

He has given several keynote lectures in major rock mechanics conferences (such as EUROCK 2010 in Lausanne, Switzerland; ISRM Congress 2015 in Montreal, Canada) and numerous other invited talks in Europe, America and Australia. Jean Sulem is also a member of the Advisory Board of several scientific journals: Acta Geotecnica, ASCE International Journal of Geomechanics, Géotechnique, Geomechanics for Energy and the Environment, Rock Mechanics and Rock Engineering.
