Abstract. With the introduction of massively parallel sequencing (MPS) technologies, we are in a position to capture pictures of the microbiome at specific timepoints. MPS allows us to consider interactions between bacteria and their environment with an accuracy greater than achieved in vitro. We describe the process from microbiome sampling to sequence production and cleaning, and the first of two homologies. We describe some of the transformations possible, including the generation of phylogenetic trees for the bacteria in a sample. We propose a means of applying persistent homology to phylogenetic trees, and speculate on the future of this application.
