Identifying principles and molecular mechanisms of bacterial self-organization, especially those governing spatiotemporal organization of bacterial cells (e.g. protein subcellular localization, chromosome dynamics and cell cycle regulation). In my lab, we use the predatory bacterium Bdellovibrio bacteriovorus, which proliferates in a non-binary manner inside other bacteria, to investigate these processes and how they are coordinated to produce a non-canonical lifestyle. To this end, we apply various approaches of bacterial cell biology including live fluorescence microscopy and quantitative image analysis at the population and single-cell levels, molecular biology, bacterial genetics and biochemistry.
