Research interests

Schwann cells possess a remarkable plasticity and are able to conduct a plethora of functions with emerging importance in tissue regeneration and neoplastic diseases. My overall research goal is to uncover the molecular mechanisms driving the versatile behavior of human Schwann cells during nerve regeneration as well as benign and malign tumor development for therapeutic exploitation.

Techniques, methods & infrastructure

• culture of primary cells of neuronal and glial origin, particularly human Schwann cells
• confocal imaging
• proteome & transcriptome expression analyses
• quantitative antibody-based read-out techniques
• co-culture experimental set-ups
• ex vivo and in vitro models of nerve regeneration
• phagocytosis / efferocytosis assays
