Dr. Bridges studies how bacterial cells form communities called biofilms that have particular three-dimensional architectures. He is investigating how the bacterial cell-cell communication process called quorum sensing drives the spatio-temporal gene expression patterns that govern biofilm formation. Biofilm bacteria are implicated as causal in various cancers and, furthermore, cancer patients receiving chemotherapy frequently suffer from infections caused by bacteria that rely fundamentally on biofilm formation for pathogenesis. By discovering the quorum-sensing program that bacteria execute to sculpt biofilm architectures, he hopes to contribute to the development of new strategies to interfere with formation of these bacterial communities.
