Education

Postdoctoral Fellow (Ames Laboratory, USDOE and Iowa State University; 1999-2005)
Ph.D. (University of Tartu, Estonia; 1999)

Research interests

  • Renewable energy: Optical spectroscopy of pigment-protein light-harvesting photosynthetic complexes - energy transfer and charge transfer.
  • Biophotonics / Protein structure and [low-temperature] dynamics - Protein-chlorophyll complexes as model systems. Heat transfer in proteins and through protein-water interfaces. Energy landscapes and dynamics in amorphous solids.
  • Biosensors for explosives detection utilizing photosynthetic reaction centers.
  • Combining optical (Raman) and transport measurements in graphene and carbon nanotubes.
