Education

  • BS, Physics, University of Athens, Greece – 1976
  • MS, Physics, Purdue University, US – 1979
  • PhD, Physics, Purdue University, US – 1983

Research Area

Specialties

Magneto-spectroscopy in the visible and near-infrared of semiconductor nanostructures and devices.

Research Interests

I am interested in the study of magneto-optical properties of semiconductor based nanostructures such as magnetic quantum dots. More recently my group has been studying two dimensional transition metal dichalcogenides.
