Microbial Morphogenesis and Growth


Our lab is interested in how bacteria control their shape and size during growth. We also study how bacteria coordinate general physiology with shape. For example, how do bacteria ‘know’ in a certain nutrient environment at what rate they have to expand their cell envelope to make space for intracellular protein, DNA, etc. ? How do they know when to divide, and when to undergo a transition into dormancy?  Our lab addresses these questions with combined techniques from physics, engineering, and molecular biology.  In particular, we are using state-of-the art fluorescence microscopy, quantitative image analysis, and modeling to decipher how bacteria organize in space and time.
