Ecology of the human early life microbiome

Marie Claire Arrieta, PhD

We know we get colonized with trillions of microbes as soon as we're born, but how does this happen? Is there an evolutionarily conserved sequence of events? And if so, which ecological process(es) drive this? How does our modern lifestyle influence this pattern of colonization during early life? These are the questions we're trying to answer using birth cohort studies in industrialized and non-industrialized countries.
