Our houses, workplaces, and even the air we breathe are teeming with microbes, some of which can cause severe illness. Dr. Catharine Bosio is an immunologist studying how airborne pathogens infect and alter cells in the lungs. Her work focuses in particular on a bacterium called Francisella tularensis, which causes a life-threatening disease called tularemia and has the unique ability to change how energy-producing mitochondria function in immune cells. Dr. Bosio's experiments with these deadly bacteria could lead to more effective ways to diagnose and treat tularemia and other infectious diseases.  

Catharine Bosio, Ph.D., is a Senior Investigator in the Immunity to Pulmonary Pathogens Section at the NIH's National Institute of Allergy and Infectious Diseases (NIAID). Learn more about Dr. Bosio and her research at https://irp.nih.gov/pi/catharine-bosio.
