Dr. Ana Weil studies the relationship between the gut microbiome and immune responses to enteric diseases. Using molecular, genomic and immunologic methods, she investigates how the gut microbiome influences susceptibility to enteric infections, modulation of immune responses by the gut microbiome, and pathogen-gut microbe interactions at the mucosal surface.

She works with several US-based collaborators and the International Centre for Diarrhoeal Disease Research, Bangladesh.

research interests

The Weil lab focused on understanding how the gut microbiota impacts enteric disease and immune responses to enteric infection. We primarily study Vibrio cholerae, the causative agent of cholera, using molecular tools and methods, immunoassays, anaerobic microbiology, genomics, imaging, cell culture, and small intestinal enteroid models. We aim to understand interactions between gut microbes, V. cholerae, and the host.

clinical interests

Dr. Weil works clinically to care for Solid Organ Transplant patients, particularly those with enteric infections.
