Kostas Danas holds a tenured position as CNRS Research Assistant Professor (Chargé de Recherche) at the Solid Mechanics Laboratory (LMS) at Ecole Polytechnique. He was born and raised in Kozani, Greece and studied at the Department of Mechanical Engineering at the University of Thessaly, Volos, Greece where he received his Dipl. in Mechanical Engineering (2003) with highest honors (rank 1st). He received his M.Sc (2004) from the University of Pennsylvania and his Ph.D. (2008) from the Ecole Polytechique, France and the University of Pennsylvania, PA, USA. After the end of his graduate studies, he moved to the University of Cambridge, U.K. as a postdoctoral Research Associate. In 2009, he applied for a research faculty position at the Centre National de la Recherche Scientifique (C.N.R.S.) where he was ranked 1st in the section of solid mechanics. His main research interests are in the field of solid mechanics and composite materials with an emphasis on the theoretical and numerical description of constitutive laws for composites. He is currently working on the modeling of microstructured active elastomers and their instabilities as well as on the fracture of metallic porous materials. He has recently been awarded an ERC starting grant (2014) to carry out research on the low energy control of instabilities in magnetorheological polymers.
