Chemotaxis, the ability of cells to detect and respond to a gradient in chemical concentration, plays a central role in microbial ecology. We develop new microfluidic approaches to create carefully controlled, spatial and temporal gradients of (single or multiple) chemical stimuli. We use these to study the motility and growth response of bacteria to transient stimuli, sensory adaptation, the integration of different signals, and the role of metabolism on chemotaxis (energytaxis).

Now working on this theme: Vicente Fernandez, Filippo Menolascina, Kwangmin Son, Yutaka Yawata (previously: Tanvir Ahmed).
