Research activities and interests
My research is focused on host-pathogen interactions between innate immune cells and pathogens, e.g. mycobacteria, HIV and lately also SARS-CoV2. Infectious diseases still represents a threath to global health and the world is in great need for new medications and vaccines. Our basic research may contribute in revealing new therapeutic or vaccine targets. The macrophage is always in focus, but we are currently establishing multicellular ex vivo infection models to study how cellular cross-talk shapes the resulting immune response. Since the discovery of the anti-bacterial functions of lipocalin 2, I have also initiated and contributed in projects exploring the role of lipocalin 2 in infectious diseases or use as a biomarker in diverse conditions.
My research group is part of a larger intitiative on molecular mechanisms of inflammation research, CEMIR.
