PhD student. Analyzing CcpA affinity to cre boxes (catabolite responsive elements) and response of B. subtilis to membrane protein overproduction stress.
I started to work with B. subtilis during my diploma thesis in Marburg, analyzing the gene expression pattern during sporulation and their control by the four sporulation sigma factors. This work was continued during my PhD thesis in Greifswald. In collaboration with Prof. Bremer and Prof. Marahiel in Marburg we also studied additional adaptation processes of B. subtilis, like the adaptation to low temperatur and high osmolarity.
I am now working as a staff scientist in Prof. Völkers lab in
The main area of my expertise concerns protein sorting and secretion in Gram-positive bacteria, such as Bacillus subtilis and Staphylococcus aureus.
The Gram-positive bacterium B. subtilis is well known for its high capacity to secrete proteins into the extracellular milieu, which has led to its exploitation as a "cell factory" for secreted proteins. Nevertheless, the secretion of heterologous proteins of pharmaceutical importance is frequently inefficient. This applied problem has been a major

I am a biologist in the lab of Prof. Reuss at the University of Stuttgart and I am working in the field of biotechnology and mathematical modelling.
I am PhD student at Prof.Uwe Voelker lab in Department of Functional Genomics. My area of research is microbial functional genomics in particular analysing the whole transcriptome(by microarray and other molecular biolology methods) of B.subtilis under various stress conditions.
I use QconCAT strategy for absolute quantification of carbon metabolic enzymes via MRM(multiple reaction monitoring) by LC-MS/MS.
I also perofrm experiments for understanding of dynamics of SigmaB network for modelling.
I am pursuing my PhD at Prof. Volker's Lab in the Department of Functional Genomics, EMA Universitat Greifswald, Germany. I am working on the general stress responses mediated by SigB and the prediction of SigB regulon members using the Random forest algorithm.

Recent studies revealed the unsuspected complexity of the bacterial transcriptome but its systematic analysis across many diverse conditions remains a challenge. Here we report the condition-dependent transcriptome of the prototype strain B. subtilis 168 across 104 conditions reflecting the bacterium's life-styles. This data set composed of 269 tiling array hybridizations allowed to observe ~85% of the annotated CDSs expressed in the higher 30% in at least one hybridization and thus provide an
