Multi-scale modeling of nano-geological processes

Significant progress in many fields depends on the development of better tools to model pro-cesses that are coupled across scales. For example, we have made significant progress in fields such as fracture, friction, and mineralization processes, but furth er progress and under-standing now depends on better models that couple the atomic and subatomic processes at interface contacts and fracture tips, with large scale transport and deformation processes. This requires models that couple atomic modeling meth ods, such as molecular dynamics models with a quantum-mechanical basis, with continuum methods. To develop competence in such modeling techniques, I propose to establish a collaboration with a world-leading group in multi-scale modeling of mechano-chemica l processes at the University of Southern California. By working in the group I will be introduced to the methods and approaches developed and apply this knowledge to develop models for friction and geological mineralization processes. The aim is to devel op a long-lasting research collaboration that will provide a modeling competence which is complementary to that found at UiO. This will strengthen the modeling competence at the department, and help build an internationally competitive environment for com putational physics. The research stay will also allow my five phd-students to have extended visits at the group, which will important for them to develop their professional network, and to establish further future collaborations between UiO and USC. The s upervision of my master and phd-students will be ensured by collaborations within the department and PGP, and through research stays at USC for the students funded through external projects.
