Dimitrios Sfyris
I am working as a Principal Researcher (Grade B) focusing primarily in the broad field of continuum mechanics. I have done research in dislocation/plasticity problems, graphene/thin films, nonlinear elasticity and elastoplasticity as well as constitutive modeling for a large class of novel materials. I use a broad spectrum of techniques from applied mathematics including group theory, partial differential equations, integral equations, integrodifferential equations and differential geometry.
