    Dr. Bachman received his MD and PhD degrees from the University of Michigan Medical Scientist Training Program. His thesis work in the Laboratory of Michele Swanson, PhD, focused on virulence gene regulation of Legionella pneumophila. He completed a Clinical Pathology Residency and Clinical Microbiology Fellowship at the Hospital of the University of Pennsylvania. He also performed postdoctoral research on the host response to Klebsiella pneumoniae iron metabolism in the laboratory of Jeffrey Weiser, MD.

    M&I Frederick G. Novy Endowed Scholarship goes to Lavinia Unverdorben
    This endowed scholarship was created in 2017 by Lynn Kitabchi, in honor of her grandfather Frederick G. Novy, a world renowned bacteriologist. In 1902, Dr. Novy established the University of Michigan Department of Bacteriology, now the Department of Microbiology and Immunology. The intent for this scholarship is to provide need-based support to Ph.D. students in M&I.
