Research interests:
We study wide band gap materials, their electronic and radiative properties. The main topics include:
• Radiation defects, investigation of their generation and healing mechanisms in fusion energy and other applicable materials.
• Theoretical modeling and experimental investigation of the properties of optical materials, in relation to the structure of the material.
• Investigations of electronic structure modification of materials, relaxation of electron excitations and ultrafast processes for applications in scintillators and other detector materials.
