Our lab is interested in post-transcriptional gene regulation in the Gram-positive model bacterium Bacillus subtilis, in particular in phenomena that affect the rate of mRNA decay. We are interested in the identification of new ribonucleases, their mRNA and stable RNA substrates, and how they are regulated. We are also interested in small regulatory RNAs (sRNAs) and understanding how they can modulate mRNA decay rates either directly or indirectly (e.g. via translation). We use molecular genetics, molecular biology and structural approaches in most of our projects
