Welcome!

The Mobley Lab was established in 1984 in the Division of Infectious Diseases at The University of Maryland School of Medicine in Baltimore. The lab moved to The Department of Microbiology and Immunology at The University of Michigan Medical School in Ann Arbor, Michigan in the summer of 2004. The Mobley Lab is comprises research professors, research technicians, undergraduates, graduate/doctoral students, and postdoctoral fellows dedicated to performing cutting edge research in the field of bacteriology. Since its inception, the lab has produced over 275 publications and trained more than 70 graduate students and postdoctoral fellows.
