Finlay Lab


Brett Finlay is a microbiologist whose research explores the interaction between pathogenic bacteria, such as Salmonella and E. coli, and their host cells.

He is particularly interested in how the microbiome of humans can affect conditions such as
asthma, inflammatory bowel disease, food allergies and cardiovascular disease. Finlay is also interested in treatment and prevention of infections such as the C. difficile bacteria. In 2003, he led the successful initiative to develop a SARS vaccine.
