MARLIES MEISEL, PHD

Principle Investigator

Dr. Marlies Meisel is the principal investigator of the lab. Marlies is passionate and eager to dissect the impact of systemic commensal signals on the immune system during health and disease. 

Marlies is a cellular Immunologist, has a strong background in Nutritional Sciences (M.S.), received her PhD from the Medical University of Innsbruck, Austria in 2012, and completed her postdoctoral training at the University of Chicago (Lab of Dr. Bana Jabri) in 2018. She started her lab at the University of Pittsburgh, Department of Immunology in October of 2018. 

Marlies does not only work with microbes in the lab; also at home she utilizes the power of microbes to brew her own beer, kombucha and sourdough bread. Besides that Marlies is a passionate triathlete and outdoor fan.
