Short presentation
Research Interests: Dynamics of electronic, magnetic and structural degrees of freedom in materials. We develop and use time-dependent density-functional theory to study laser driven dynamics. We aim to advance these methods to treat correlated materials by incorporating aspects of dynamic mean field theory in to the real-time formulation of time-dependent DFT.
