Department of Civil and Environmental Engineering at Virginia Tech. He obtained his Diploma in Civil Engineering from the National Technical University of Athens, and his M.Sc. and PhD degrees from UC San Diego. His research interests include constitutive modeling of inelastic materials, analytical performance assessment and retrofit of reinforced concrete, steel and masonry structures, and experimental evaluation of materials and structures. In 2012, he received the Outstanding Doctoral Dissertation Award from The Masonry Society (TMS), for his doctoral work on the analytical and experimental investigation of the seismic performance of masonry-infilled reinforced concrete frames. He is a voting member of the joint ASCE/ACI Committee 447, Finite Element Analysis of Concrete Structures.
