Microbiology
Microbiology (from Greek , "mīkros", "small"; , "bios", "life"; and , "-logia") is the study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, parasitology, mycology and bacteriology.
Alison Murray (scientist)
Murray's research has provided critical insights into how microorganisms persist and function in extremely cold and harsh environments, including those that lack oxygen and biological sources of energy. Making use of molecular genomic tools to describe microbial life, her work has helped answer questions about how microbes function and survive in extremely cold environments and how environmental changes affect the functioning and diversity of these organisms, as well as potential feedbacks that might impact the sustainability of cold-environment ecosystems.
