"Our research group applies and develops computational tools to
understand light-induced processes in condensed matter. On the
application side, the focus is on excited state reactions, especially in
solvated molecules and chromophore-protein complexes that occur in
nature. To this end, we apply multiscale methods that allow the
calculation of systems with thousands of atoms. On the development side,
the group is interested in computational tools that can accurately
describe the excited states. The focus is on multireference methods that
are flexible in describing the electronic wavefunction at critical
points for excited state processes. Such critical points include
degeneracies of different electronic states, for example conical
intersections."
