Our research is centered on modeling the behavior of complex physical and chemical systems. We are particularly interested in the description of quantum effects in the emerging behavior of systems of nanoscopic dimensions. Nanosystems may have very different optical, magnetic, chemical and electrical properties compared to the bulk system of the same material. Size and quantum effects determine these variations and we try to describe how they translate into the observed experimental behavior.

Our research is strongly guided and influenced by the interaction with experimental groups. This is of special importance in the modeling of nanosystems because of the complexity of the emerging physics and chemistry. We have ongoing research efforts with a strong international cooperation in several major areas:

  • Electron transport in molecule-electrode interfaces.
  • Electron transfer.
  • Nanophotonics.
  • Nanomagnetism.
  • Solar energy.
