1. Theory and Application of the Mechanics of Graphene Sheets
Abstract : Starting from an atomistic approach, I derive a hierarchy of successively more simplified continuum elasticity descriptions for modeling the mechanical properties of suspended graphene sheets. It is shown that graphene sheets with clamped edges have an intrinsic nonlinear mechanical response due to a variable tension induced by stretching. READ MORE

3. Computational studies of graphene and single walled carbon nanotube growth and carbonaceous polymeric nanocomposites
Abstract : Graphene and single walled carbon nanotube (SWNT) has attracted a lot of attention in different fields of science due to its unique electrical, mechanical, and optical properties. Controlling the growth of graphene and SWNT is a very topical subject and critical for producing material with desired properties since their properties are highly dependent on their atomic structure and it is often desirable that the material contains very few or (if possible) no defects.

4. On error controlled atomistic-to-continuum modeling with application to graphene monolayers
Abstract : In order to consider virtual materials, i.e. materials that are not manufactured yet, it can be advantageous to model physical phenomena on a lower length scale than the macroscopic one. In such a case, homogenization (or coarse-graining) can be a useful tool. READ MORE

5. Modelling of Molecular-Scale Nanoelectromechanical Systems
Abstract : Nanoelectromechanical systems (NEMS) couple electronic and mechanical degrees of freedom in a nanoscopic structure. The small size introduces many atomistic and quantum mechanical features which on the one hand open up for interesting new features and possibilities but on the other hand make it very difficult to formulate quantitative predictions.
