Research interests

Schwann cells possess a remarkable plasticity and are able to conduct a plethora of functions with emerging importance in tissue regeneration and tumor development. My overall research goal is to uncover the molecular mechanisms underlying the functional spectrum of human Schwann cells to exploit this knowledge in novel therapeutic approaches for patients suffering from nerve injuries. I explore how human Schwann cells interact with the environment during nerve regeneration but also during benign and malign tumor development to eventually design therapies for targeted Schwann cell modulation in pathologies of the peripheral nervous system.

Techniques, methods & infrastructure

• culture of primary cells of neuronal and glial origin, particularly human Schwann cells
• multicolor immunofluorescence stainings
• confocal imaging
• proteome & transcriptome expression analyses
• quantitative antibody-based read-out techniques
• co-culture experimental set-ups
