Sarah Bagby

Sarah Bagby is an Assistant Professor at Case Western Reserve University researching how environmental variables drive microbial and viral evolutionary innovations that reshape Earth's biogeochemical systems.

Her primary research domains include:

• Microbiology
• Environmental Science
• Evolutionary Biology
• Bioinformatics
• Biogeochemistry
• Molecular Biology

Her lab employs integrated methodologies including fieldwork to characterize in situ microbial communities, experimental ecology/microbiology to identify molecular innovations (e.g., cyanobacterial microcompartments, phage pigment pathways), and ecoinformatics to model ecosystem impacts. This work examines how pressure, temperature, irradiance, and fluid dynamics influence microbial membrane structures, energy harvesting, and genetic diversification mechanisms across temporal and spatial scales.
