  Persönliches Profil:

Als wissenschaftlicher Mitarbeiter im Labor für Gehirn und Sprachforschung befasse ich mich mit den neuronalen Grundlagen von Bedeutungsverarbeitung.

Dazu untersuche ich unter anderem die Sprachfähigkeiten von Patienten mit einer Hirnschädigung (z.B. nach einem Hirntumor oder einem Schlaganfall), um Aussagen über die funktionalle Rolle der betroffenen Hirnareale treffen zu können. Im Rahmen unserer Sprachtherapie-Studie versuche ich zusätzlich, mittels funktioneller Magnetresonanztomographie (fMRT), die neuronalen Korrelate für Verbesserungen der Sprachleistung bei unseren Patienten zu finden.

Personal Profile:

Before I started working at the Brain and Language Lab at the FU Berlin in November 2012, I finished my MSc at the University of Leipzig and my BSc in Cognitive Science at the University of Osnabrück.

My studies included several research stays at external institutions, among others the Medical Research Council, Cognition and Brain Sciences Unit in Cambridge, UK and the Embodied Cognition Lab at the University of Manchester, UK.

Research Interests:

I'm interested in theories of embodied cognition and how they could help to understand the processing of linguistic semantics on a single word or sentence level. In my work I investigate whether these theories can also be applied for abstract words, which do not have transparent sensorimotor components. To do so, I am utilizing fMRI and neurostimulation approaches and perform studies on patients suffering from stroke (in collaboration with Prof. Helmut Hildebrandt from the University of Oldenburg) or brain tumors (in collaboration with Dr Thomas Picht from the Charite University Hospital, Berlin).
