fungal infection • pneumonia • sepsis • forward genetic analysis • innate immunity
My research focuses on identifying and characterizing molecules that are essential for protection against progressive respiratory and/or systemic infection (pneumonia and sepsis) using mouse models that accurately represent human disease. We use several genetic approaches to identify host susceptibility factors and combine this with detailed immunological analysis of the defective genes and their respective pathways. We are also developing protocols to study these molecules in critically ill patients with severe infections. A comprehensive understanding of the molecular foundation of protective immunity will lead to the development of new prevention and treatment strategies against the relentless microbial threat to human health.
