PREDICTING WATER MICROBIOME COMPOSITION AND DYNAMICS
Our recent study discovered that bacteria in tap water rapidly assemble into highly stratified community compositions upon stagnation in residential buildings. Employing an ecological null model and chemical reaction kinetics models further revealed the role of physical characteristics common to modern plumbing designs in shaping the chemical environment and regulating bacterial growth and dispersal. Motivated by these findings, we are developing and validating models that integrate phylogenetic and functional dimensions of bacterial communities to predict water microbiome dynamics.
