Drew Bridges

Drew Bridges is an Assistant Professor in the Department of Biological Sciences at Carnegie Mellon University. His research focuses on bacterial group behaviors, biofilm communities, bacterial signal transduction, and live-cell imaging. In the Bridges lab, the emphasis is on understanding how bacteria make developmental decisions based on extracellular sensory information, particularly in the context of biofilm formation and disassembly. The lab combines imaging approaches with genetics, biochemistry, and biophysics to study molecular mechanisms controlling biofilm dispersal. The lab recently relocated to the historic Mellon Institute building at Carnegie Mellon University. His work aims to uncover principles governing bacterial lifestyle changes across multiple scales and its relevance to infection control.

Andrew A. Bridges is an Assistant Professor of Biological Sciences at Carnegie Mellon University, specializing in Microbial Physiology, Signal Transduction, Microscopy, and Biofilms. His research explores the molecular mechanisms governing bacterial collective behaviors, including biofilm formation and dispersal, with a focus on Vibrio cholerae. Using advanced microscopy techniques, Bridges investigates how signaling pathways and quorum-sensing systems regulate microbial interactions. His work also examines the role of septin cytoskeletons in membrane curvature recognition and cell cortex organization. By integrating biochemical, genetic, and imaging approaches, Bridges seeks to uncover the principles of signal transduction networks in microbial communities.
