His research interests are focused on:
- Theoretical study of structural, electronic and optical properties of nanostructured materials by means of first principles calculations and advanced techniques from the field of quantum chemistry.
- Study of semiconductor nanostructures (nanorods, nanowires) consisting of thousands of atoms by means of the Empiric Pseudopotential Method (EPM).
- Phenomenological calculations in the framework of the Effective Mass Approximation (EMA).
- The whole spectrum of properties and problems which may be modeled by ab initio and semiempirical calculations
