Research interests
My past work has left me especially fascinated with large-scale networks in the human brain and their role in clinical deficits in patients suffering from brain disease. I particularly aspire to a job in a research lab or neuroimaging center that combines different imaging techniques and modalities to study brain diseases. An integrated approach should provide valuable insights into the relation of changes in brain morphology, anatomical connectivity, functional connectivity to changes in neuronal networks and their pathophysiological role in brain disease.

Ample experience with standard clinical assessments of cognitive and affective functions, computerized neuropsychological assessments (Cambridge Neuropsychological Test Automated Battery & Vienna test System) as well as with testing of olfactory function (Sniffin’ Sticks and UPSIT) in controls, demented and non-demented Parkinson’s disease patients.
