Rachel L. Simister

My research interests span the broad field of microbial interactions and ecology, incorporating varied disciplines such as molecular biology, phylogenetics, biogeochemistry and biotechnology. My work is highly interdisciplinary, centring on the analysis of microbial communities from a wide variety of environments and putting these comparisons in a temporal and spatial context. My research focuses on both free-living and host-associated bacteria and archaeal communities, as well as eukaryotic (fungal) microbial communities. My ultimate goal is to understanding how microbes interact with their environment and in particular, how biogeochemical variables shape community structure and function.
