The O'Riordan lab is in the Microbiology & Immunology Department of the University of Michigan Medical School in lovely Ann Arbor, MI.  M&I is one of the oldest microbiology departments in the country and was recently named as a "Milestones in Microbiology" site by the American society of Microbiology.

Our research explores the molecular interactions between bacterial pathogens and mammalian host cells, using cell biology, biochemistry and small animal models.  Of particular interest are cells of the innate immune system, like macrophages, which act as a first line of defense against infection.
