Prof. Lignos teaches graduate and undergraduate courses in seismic design, nonlinear behaviour of steel and composite structures as well as supplemental damping systems, Structural Stability, Nonlinear Analysis and Performance-based Earthquake Engineering. His awards for teaching, research and service in Civil Engineering include the 2011, 2021 Outstanding Teaching Awards (Faculty of Engineering, McGill University, Civil Engineering Institute, EPFL), as well as the Outstanding reviewer (2012, 2013, 2021) 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. 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. He joined the Editorial Board of Earthquake Spectra and Earthquake Engineering and Structural Dynamics International journals. He 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 1-1 and 1-2 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 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-steel concrete structures under multi-hazards. Recent work focuses on the utilisation of innovative materials and protective systems 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.
