  • Understanding the immune-modifying capacity of gastrointestinal and airway microbes through the lens of allergy

Research Abstract:

My overarching interest is to understand the immune-modifying capacity of gastrointestinal and airway
microbes through the lens of allergy. Two primary questions under investigation in the Kau lab are:

1) How do the respiratory and gastrointestinal microbiota contribute to asthma pathogenesis?

2) What role does intra- and interpersonal variation of the human microbiota and the mucosal immune response
play in human asthma pathogenesis?

Dissecting the relationships between the microbiota and immune system will have implications for human health and will require a multi-disciplinary approach incorporating expertise in microbial ecology and genetics, immunology, nutrition, technology development, computational biology and gnotobiotic mouse husbandry. I envision that the clinical and scientific relevance of this research will foster collaboration and scientific discovery and lead to novel approaches of diagnosing, treating and ultimately preventing allergic diseases.
