Biography

I received my B.Sc in Physics in 1994 and my PhD in Engineering in 2004 from Aristotle University of Thessaloniki, Greece. From 2002 – 2004 I worked as a consultant at Hyperco in Thessaloniki, Greece. In 2004 I moved to the School of Mechanical and Materials Engineering of Washington State University as a Research Associate. In 2006 I became Visiting Assistant Professor, and in 2011 a Clinical Assistant Professor at the same School. In 2014 I moved to the Mechanical and Aeronautical Engineering at Clarkson University as an Assistant Professor, a position I hold until today. My current research focuses on the mechanical properties and applications of nanoscale composite nano foams, and on the deformation behavior of High Entropy Alloys.

Research Interests

My research interests span the areas of mechanical properties of nanomaterials and new materials design driven by computer simulations. A common thread in this research is the understanding of the underlining mechanisms at the nanoscale, responsible for the deformation and fracture of metallic materials. For that purpose, computer simulation techniques that span various length scales, ranging from the nanoscale to the microscale are used. These techniques include methods such as Molecular Dynamics, Monte Carlo, Dislocation Dynamics and Finite Elements.

Broadly speaking, my research belongs to the area of Nanomaterials Science (which deals with the understanding of the fundamental mechanisms of deformation and fracture at the nanoscale), an upcoming field which is still in its infancy and whose theoretical foundations are just being laid. This research work not only has theoretical but also practical significance, due to the various potential applications of nanomaterials that include, among others, advanced coatings, smart sensors, solar energy converters, nanophotonics, opto-electronics and catalysts.

Current Research

My current research focuses on the deformation and fracture of nanoscale metallic composites and nanofoams, the mechanical properties of composite nanowires, the effect of irradiation on steels, crack-dislocation interactions, and the deformation and fracture of aluminum alloys. A variety of computational techniques like molecular dynamics and statics, Monte Carlo, dislocation dynamics and finite elements are used to investigate the materials’ behavior across length scales.
