CE/ME 551 Theory of Elasticity
My Research is focused on structure-property relationships with special emphasis on biomaterials, nanofibers and polymers. I am particularly interested in nanoscale materials property characterization using techniques such as contact resonance force microscopy (CR-FM) and Nanoindentation. For this research, I develop theoretical constitutive models and perform experiments to validate the models.
