Mayer-Barber Research Group

We are a group of dedicated scientists who work in a highly collaborative, team-oriented, and supportive environment. Together, we tackle difficult questions of chronic inflammation and innate immunity in lung diseases. Our experimental approach to query the immune system is to use animal models of pulmonary pathogens that affect thousands of Americans and millions of people worldwide.

I am visiting from the immunology and microbiology department at the Dasman Diabetes Institute in Kuwait, where my research centers on bioactive lipids and their role in diabetes and obesity. At NIH, I will leverage my background in lipid metabolism to establish techniques such as MALDI imaging to investigate the impact of key metabolic pathways on infectious diseases, particularly Mycobacterium...

The focus of my research is to understand the cellular and molecular mechanisms of type I IFN induction upon Mycobacterium tuberculosis infection in conditions of IL1R-signaling deficiency. We aim to elucidate how type I IFNs and limiting the IL-1 pathway regulate pathology, tissue necrosis, and cell death pathways.

I am working on determining mechanisms of fibrosis and tissue remodeling in the lung following Mtb infection. More precisely, my aim is to decipher how the inflammatory cytokines related to Mtb infection, such as IL-1, can trigger or regulate these processes and who are the main actors of them.
