Department of Microbiology & Immunology
Unlock the Mysteries of the Microbial World

Bacteria, viruses, parasites and fungi are all organisms that can interact with the human body, making us either healthy or sick. Our research spans from the cell to the organ, to the body and to the global population, investigating and impacting the very foundations of human health.

Training the next generation of scientists

Here, graduate students and postdoctoral fellows work side-by-side with principal investigators, testing hypotheses of significant medical importance with the potential to translate into medical advancements. This groundbreaking laboratory training is supplemented with rigorous coursework, seminar series, journal clubs, and the presentation of research findings at national meetings.

    M&I Teresa O'Meara is a recipient of of the Investigators in the Pathogenesis of Infectious Disease (PATH) program of the Burroughs Wellcome Fund. Her lab will further study the mechanisms of attachment and virulence for C. auris, with a focus on how the novel adhesin contributes to pathogenesis. On a practical level, their work will suggest strategies for developing vaccine candidates and therapeutics to limit disease caused by this emerging pathogen.

    Commonly used antibiotic brings more complications, death in the sickest patients
    In emergency rooms and intensive care units across the country, clinicians make split-second decisions about which antibiotics to give a patient when a life threatening infection is suspected. Now, a study reveals that these decisions may have unintended consequences for patient outcomes.

    Too much iron can cause big problems for the immune system
    A study builds on previous work that found depriving T cells of iron prevented cells from proliferating. The current study, published in PNAS, found that excess iron is just as problematic.
