Zacharias was born in Heraklion, Greece in 1987. He holds a Diploma in Civil Engineering (specialty on Structural Engineering) from National Technical University of Athens (years 2005-2010) and an MSc in Analysis and Design of Earthquake Resistant Structures from the same university (2012). Since then, he is working as a Design Structural Engineer as a freelancer. He re-joined the Institute of Steel Structures of NTUA in 2014, starting his PhD studies in ‘Design of lattice towers with members from cold-formed angle sections’. His research also focuses on stability of structures (especially when dealing with energy transmission/telecommunication towers), finite element analyses with stochastic processes, mechanical properties of steel during and after fire events. He has participated in several research projects, co-funded by the EU and Greek agencies.
