Computational Materials Science Group<\/p>\n\n\n\n

Ioannis Mastorakos, Ph.D.<\/h1>\n\n\n\n

Associate Professor, Mechanical & Aerospace Engineering
MAE Program Lead, Clarkson University<\/p>\n\n\n\n

We use molecular dynamics, dislocation dynamics, crystal plasticity, and finite element methods, alone and coupled across length scales, to predict how defects control the strength and deformation of metallic materials.<\/p>\n\n\n\n

About<\/p>\n\n\n\n

Simulation-driven design of stronger metals<\/h2>\n\n\n\n
\n
\n

Ioannis Mastorakos is an Associate Professor in the Department of Mechanical and Aerospace Engineering at Clarkson University and, since July 2026, the MAE Program Lead. He received a B.Sc. in Physics (1994) and a Ph.D. in Engineering (2004) from Aristotle University of Thessaloniki, Greece, and worked as a consultant at Hyperco in Thessaloniki from 2002 to 2004.<\/p>\n<\/div>\n\n\n\n

\n

In 2004 he joined the School of Mechanical and Materials Engineering at Washington State University as a Research Associate, later serving as Visiting Assistant Professor (2008) and Clinical Assistant Professor (2011). He joined Clarkson in 2014 as an Assistant Professor and was promoted to Associate Professor in 2020. His group studies plasticity in high-entropy alloys, polycrystals, and nanostructured metals, combining atomistic and mesoscale simulations with machine-learning surrogates and experimental validation.<\/p>\n<\/div>\n<\/div>\n\n\n\n
