Single-cell measurements of size and stress response, and a branching model of bacterial filamentation.
Growth and stress-response measurements inform structured models of bacterial populations.

My work on Escherichia coli combines single-cell observations with stochastic models of growth, division and phenotypic switching under antibiotic stress.

DNA-damaging antibiotics can change the growth strategy of bacteria, and cells do not respond uniformly. The nutritional environment also affects these responses. I use structured, measure-valued population models to study how these individual differences shape population growth and heterogeneity.

This work formed the core of my doctoral research, supervised by Sylvie Méléard and Meriem El Karoui at CMAP, École polytechnique.
