BiographyProf. Lignos joined the École Polytechnique Féderale de Lausanne (EPFL) in 2016 from McGill University in Canada where he was a tenured Associate Professor and a William Dawson Scholar for Infrastructure Resilience. He holds a diploma (National Technical University of Athens, NTUA, 2003), M.S. (Stanford University, 2004) and Ph.D. (Stanford University, 2008). In addition, he was a post-doctoral scientist at Stanford University (2009) and in Kyoto University (2010).
Prof. Lignos teaches graduate and undergraduate courses in Seismic Design, Nonlinear Behaviour of steel structures, Structural Stability, Nonlinear Analysis and Performance-based Earthquake Engineering. His awards for teaching, research and service in Civil Engineering include the 2011 Outstanding Teaching Award from the Faculty of Engineering at McGill University, as well as the 2012 and 2013 Outstanding reviewer award from ASCE, the 2013 State-of-the-Art in Civil Engineering Award by ASCE and the 2014 Christophe Pierre Award for Research Excellence - Early Career from the Faculty of Engineering at McGill University. Just recently, he received the 2019 Walter L. Huber Civil Engineering Research Prize from ASCE for significant contributions in developing state of the art methods to simulate extreme limit states in steel structures.
Prof. Lignos is a member of ASCE and the Earthquake Engineering Research Institute. He acts as an Associate Editor for Metal Structures and Seismic Effects of the ASCE Journal of Structural Engineering and he joined the Editorial Board of Earthquake Spectra and Earthquake Engineering and Structural Dynamics International journals. Professor Lignos serves as an acting member of the CEN/TC 250/SC 8/WG 2 and has been selected as a member of the Project Team (PT2) for the Eurocode 8-Part 1 Current Revisions for Steel and Composite Structures. He is also a member of the Canadian Standards Association (CSA) S16 technical committee for Steel Structures. Prof. Lignos is involved as a NEHRP consultant in numerous research-to-practice projects related to the behaviour and nonlinear modelling and analysis of steel structures applicable to the engineering practice through the Applied Technology Council (ATC).

ResearchMy work integrates simulation-based engineering science and the use of experimental methods for the risk and life-cycle cost quantification of steel and composite structures under multi-hazards. Recent work focuses on the utilization of innovative materials for multi-hazard risk mitigation and the development of multi-scale model techniques along with open access tools for elucidating the influence of deteriorating mechanisms on the structural performance of structures with emphasis on seismic loading. Check periodically our resslabtools.epfl.ch website for recent developments on database and integrated numerical models.
