Over 110 papers in international journals with more than 6500 independent citations and two book chapters as well as an edited book. Hirsch index: 42 (according to WoS).
One of the principal developers of the COLUMBUS and CFOUR program packages.
Method development: Multireference Averaged Quadratic Coupled Cluster (MR-AQCC) method, a Coupled Cluster based modification of MR-CISD which allows the nearly size extensive treatment of real multireference problems. Analytic derivative techniques for MR-CISD, for the TD-CC and other MR-CC methods, as well as analytic second derivatives for UHF-CCSD(T) technique. Spin-restricted coupled cluster theory for ground and excited states. Analytic techniques for high-level post Born-Oppenheimer quantities.
Application in spectroscopy: Resonance model for formamide, Renner-Teller effect in ketenyl and tioketenyl radicals, tautomers of cytosine and their excited states, excited states of DNA building blocks, hydration of cytosine, potential energy surface of ozone.
