Description of research and teaching

My research

I am interested in the basic mechanisms involved when bacteria infect the human host. My research group studies at the molecular level the secretion, biogenesis and function of bacterial surface proteins and protein appendages involved in infectious processes. We also apply these bacterial protein complexes in extracellular secretion and surface display of heterologous proteins with the aim to generate biotechnological, medical or diagnostic applications.
