Dirk Robert Rehn

I am a postdoctoral researcher in the division of Theoretical Chemistry and Biology at KTH. My research focus lies on the development of quantum chemical models for the description of electronically excited states of molecular systems. I am working on the development of linear and non-linear damped response theory for the description of UV/Vis and X-ray absorption and emission phenomena. Specifically my main focus lies on the development and extension of the Algebraic Diagrammatic Construction scheme (ADC).

My previous and current projects include the developments and implementations for:

• damped linear and non-linear response theory 
• analytical gradients
• two-photon absorption cross-sections
• excited state absorption
