Clinical Senior Lecturer


Undergraduate medical training at the Charité Medical University Berlin, Germany. Research degree ( in pharmacology with thesis on nitric oxide receptor (summa cum laude, 1996).

1997 - 2000 post-doctoral scientist with Ivan Horak at the Institute for Molecular Pathology, Berlin (immune-pathogenesis in IRF8-deficient mice).

2000 – 2004 specialist training in Dermatology at the Charité Medical University with research focus on immune-pathogenesis in psoriasis.

Certified specialist in Dermatology (2004), sub-certified in Allergy (2005).

2004 – 2007 consultant dermatologist at Charité Medical University Berlin; clinics in general dermatology and immune-dermatology; career-development grant by Deutsche Forschungsgemeinschaft. Continued research in genetics and immune-pathogenesis of psoriasis, clinical research in scleroderma (see Publications).

2007 – 2009 fellow in cancer immunology, University of Dundee and honoroary loc. Consultant (NHS).

2009 – present senior clinical lecturer, continued work in immune-pathogenesis of psoriasis, and immune-pathology of skin cancer (see Publications).

2010 – present, GCP-certified; local site coordinator of psoriasis clinical research; principle investigator in early and late phase multi-center trials of immune-intervention in psoriasis.


Currently on-going research is centered on immunotherapy of skin diseases. Projects include on-going investigational clinical trials, translational research projects, and studies addressed at genomic, pharmaco-genomic, and health-economic topics.

Please inquire for openings if interested.
