B. Brett Finlay Microbiologist

Brett Finlay‘s research explores the interaction between pathogenic bacteria, such as Salmonella and E. Coli, and their host cells. He is particularly interested by how the microbiome of humans can affect conditions such as asthma, inflammatory bowel disease, food allergies, and cardiovascular disease. He is also interested in treatment and prevention of infections, such as the C. difficile bacteria, and was the leader of the successful initiative to develop a SARS vaccine in 2003.
