Introducing the EKA Materials Research Group

We enjoy working on challenging problems in materials research in which the unifying theme is nonlinearity in its broadest sense. Currently, we endeavor to contribute to the solutions of nonlinear problems appertaining to vapor phase mass transport in highly tortuous solids, nonlinear electrostatics of dielectric interfaces, and nonlinear elasticity in structural phase transformations, to name but a few. Recent research focuses on 3D stereolithography and sintering of UHTC for hypersonic applications
