• Structural studies on natural products with quantum chemical methods
• prediction of optical properties of organic and organometallic molecules with a special emphasis on chiroptical properties by TDDFT or MRCI methods
• Elucidation of absolute configurations of organic molecules by a combination of experimental and quantum chemically predicted spectra (NMR, UV, ECD)
• development of SpecDis
