A warm welcome our two new lab members, Emma and Massimo. Emma is a visiting postdoc who will be modelling the establishment of new inversions in a population. And Massimo has joined both Isabel Gordo’s lab and our lab as a PhD student. He will be building a gene-based mathematical model to investigate the mechanisms and effects of evolutionary change on the dynamics of mammalian microbial communities regarding their stability, diversity, interactions, and effects on the fitness of the host.
