  Research Interest 

Our laboratory's primary research focus is how infections and less invasive exposures to microbes impact on the patho-genesis of allergic diseases. In particular, we are actively investigating the immunological activities of microbial products that activate cells through toll like receptors and the immunomodulatory effects of toll like receptor ligands in allergic disease models.
