In this thesis we introduce two theoretical frameworks, one at the macroevolutionary scale with which we find universal quantitative similarities in the tempo and mode of microbial diversification, and the other at the mesoscopic scale where we discover a rich hierarchy of organization and niche signals in the pattern of microbial abundances in the global ocean and in the process identify three putatively novel microbiomes.

We introduce a theoretical framework to quantify the effect of ecological innovations in microbial evolutionary history, using a new, coarse-grained approach that is robust to the incompleteness and ambiguities in microbial community data.

We investigate the entanglement between a spin and its environment in impurity systems which exhibit a second-order quantum phase transition separating a delocalized and a localized phase for the spin.
