The authors first developed a mathematical model of resistance to predict how good or poor hygiene might affect how rapidly resistant bacteria increase in abundance due to antibiotic treatment. Kristofer Wollein Waldetoft, a postdoctoral researcher with the Center for Microbial Dynamics and Infection (CMDI) in the School of Biological Sciences, and Sam Brown, professor in the School and former CMDI director, collaborated on the research.
