Our research interest is focused on developing analytical and computational multiscale techniques, and applying these techniques to engineering and biomedicine. Some current application topics include (i) response of charged defects to electric fields in solid oxides and ferroelectrics for energy applications; (ii) mechanics of drug transport across biological membranes; (iii) electron transport in deformed biomolecules under stress; (iv) response of nanostructured materials under dynamic loading for impact and blast protection; (v) composite functional materials for high-temperature sensors and actuators for hypersonic aircraft; (vi) quantum mechanical calculation of electromechanical properties of nanomaterials (graphene, nanotubes, chalcogenides)
