University of Arizona

Dr. Michael D. L. Johnson is an assistant professor in the Department of Immunobiology at the University of Arizona. He received an A.B. in Music from Duke University and his Ph.D. in Biochemistry and Biophysics at the University of North Carolina at Chapel Hill. After completing his dissertation in bacterial motility and attachment, he went to St. Jude Children’s Research Hospital in the Department of Infectious Disease to study how bacteria process nutrients, specifically metals, during bacterial infections. He then worked in the Department of Immunology studying newly discovered ways that the body eliminates harmful pathogens. During his postdoctoral fellowship, he also founded Science Sound Bites, a science podcast for kids.

At the University of Arizona, he studies mechanisms of metal toxicity in bacteria. Specifically, his laboratory asks how copper is toxic to microbes, how the microbes fight back against this stress and whether it is possible to weaponize copper as a therapeutic. He is active in science outreach through events like founding the National Summer Undergraduate Research Project and The BIO5 Postdoctoral Fellowship Program, and in scientific and educational affairs concerning underrepresented groups through the ASM Subcommittee on Microbiological Issues Impacting Minorities.
