Short Bio

Education
1997-1999 PhD in Physics, University of Modena, Italy.

Appointments
- March 2003 - present: CNR-NANO Research Center S3, Modena, Italy. Research staff.
- December 1999 - February 2003: Department of Physics, University of Modena, Italy. INFM Postdoctoral Researcher.

Research Interests

  • Theoretical investigation of few- and many-body effects in nanostructures and low-dimensional systems.
  • Long-range interactions in quantum materials and permanent Bose-Einstein condensation of excitons by combining first-principles and model approaches.
