Research in the Tschowri group

Our research themes:

  • Cyclic di-GMP signalling and regulation in bacterial cell differentiation
  • Cyclic di-AMP enzymes and effectors in Streptomyces stress response
  • Bacterial multicellularity and cell fate decisions
  • Nukleotide signals in bacterial carbon storage
  • Small molecule signalling in Streptomyces’ cell division

Prof. Dr. rer. nat. Natalia Tschowri

Natalia Tschowri studied Biology at the Freie Universität Berlin, where she also obtained her PhD with a thesis on blue light signalling in the control of biofilm formation in Escherichia coli. In September 2012 she joined Prof. Mark Buttner’s lab at the John Innes Centre in Norwich, UK, as a PostDoc. Funded by the EMBO longterm fellowship, she began to work on c-di-GMP signalling in Streptomyces. Back in Berlin, she continued with her studies on the role of cyclic di-nucleotides in Streptomyces developmental biology as an Emmy Noether-Programme-funded group leader at the Humboldt-Universität zu Berlin. Since October 2020, she is a professor for cellular micobiology at the LUH.

The Faculty of Natural Sciences welcomes Natalia Tschowri [in German]
