Research interests 

Our laboratory investigates fundamental mechanisms of regulation of bacterial biofilm development with a focus on human pathogens. We are interested in understanding how signal transduction systems control the transition between planktonic and sessile lifestyles. We also study the composition of biofilm matrix and the function of these compounds during infection. In particular, we do research on basic principles of RNA overlapping transcription and its role in gene expression, on mechanisms of exopolysaccharide synthesis regulation and on how surface proteins of the biofilm matrix mediated intercellular adhesion and interactions with the host cells. Very recently, we have deconstructed the two-component signal transduction system of Staphylococcus aureus. In this study, we have generated fifteen S. aureusstrains, each containing just a single TCS, as well as a mutant lacking all 15 non-essential TCS. This powerful and unique genetic resource will allow us to unambiguously determine the contribution that each individual TCS to the regulation of peptidoglycan biosynthesis and antibiotic resistance.
