Brief CV

TEACHING

My research interests are mainly in Theoretical Atomic Physics, and I do my research in the Centre for Theoretical Atomic, Molecular and Optical Physics (CTAMOP).

Selected topics:

• Many-body theory in atoms.
• Electron-atom scattering, negative ions, photodetachment.
• Interaction of positrons with atoms and molecules: scattering, bound states and annihilation.
• Quantum chaos in complex atoms and other many-body systems.
• Multiphoton processes in strong laser fields.
• Cold atom scattering.
