Neutrophil biology in health and inflammation

Neutrophils are innate immune cells with diverse roles in homeostasis and immunopathology. They are paramount for a viable defense against invading pathogens, orchestrate immune responses with other immune cells and help repair tissues. In contrast, they are strong drivers of tissue damage in immune mediated diseases. Neutrophils are currently not directly being targeted therapeutically. Our overall research agenda is aimed at developing ways to selectively intervene with pathologic neutrophil functions without compromising host defense. We work towards this goal by studying neutrophil heterogeneity in both healthy tissues as well as pathologic inflammation in humans and mice. We study neutrophils on the systems immunology level using high dimensional technologies to understand the driving forces behind their fascinating adaptation to different tissues and inflammatory conditions. We are always seeking motivated postdoctoral fellows and graduate students to join the neutrophil biology team!
