Research activities and interests
My research is focused on host-pathogen interactions between innate immune cells and bacterial pathogens, e.g. mycobacteria and uropathogenic E. coli. The focus on mycobacteria comes from an interest in Global Health issues, in particular infectious diseases like tuberculosis where the world is in great need for new medications and vaccines, and where our basic research may contribute in revealing new therapeutic or vaccine targets. The macrophage is always in focus, but since the discovery of the anti-bacterial functions of lipocalin 2, I have 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.
