Research interests

From 1990 to 1999, I investigated the structure, function, assembly, and dynamics of bacterial outer membrane proteins. For this purpose, I used the proteins OmpA (a protein of structural importance), OmpF (a non-specific porin), LamB (a specific porin), and FhuA (a TonB-dependent receptor) from Escherichia coli as model systems. In particular, OmpA served as a paradigm for the design of artificial membrane proteins.
In 1999, I started to work on the type III secretion mechanism of the plant-pathogenic bacterium Xanthomonas. From 2002 to 2005, I coordinated the high-quality manual annotation of the Xanthomonas euvesicatoria genome sequence (strain 85-10) at the Institute of Genetics of the Martin Luther University of Halle-Wittenberg (Laboratory of Prof. Dr. Ulla Bonas) and since then I went into comparative genomics and data mining in order to identify novel pathogenicity factors.
In 2006, I launched a new research project focussing on the interaction between rice-pathogenic Xanthomonas oryzae and its host plant at the Institut de Recherche pour le Développement in Montpellier. Since then, I have worked on various aspects of diagnostics, genetic diversity, pathogen-plant interaction and genome editing for resistance to infection, using several Xanthomonas species as research subjects. In view of my not-too-distant retirement, I would advise against contacting me about any job offers.

Teaching duties

From 2000 to 2006, I organized practical courses in basic and advanced genetics. Furthermore, I gave lectures and seminars in genetics, microbiology, plant biotechnology, phytopathology and bioinformatics, all at the Martin Luther University of Halle-Wittenberg.
