Research

Our research focuses on the structure and function of collagenous carbohydrate binding proteins known as collectins. We are investigating the structure, function, synthesis, assembly and secretion of Surfactant Protein D (SP-D) - a collectin that plays important roles in the innate pulmonary host defense against a wide variety of important bacterial, fungal, and viral pathogens. The laboratory currently is using site-directed mutagenesis and crystallographic analysis to examine mechanisms of microbial pattern recognition.
