The Bay Group
Microbial Ecology, Biogeochemistry
& Global Change
MISSION
We advance research on the microbial ecology of terrestrial and aquatic ecosystems, tackling global challenges including environmental degradation, food security, and climate change. We mentor future leaders and scientists in an inclusive and collaborative setting that fosters innovation and a deeper understanding of complex systems.
RESEARCH
Three Integrated Themes
Theme 1
Biodiversity,
Function & Activity
Microbes thrive in diverse and extreme habitats like deserts, salt lakes, caves, and the deep ocean, defying the notion that these environments are too extreme for life to persist. Our research reveals that many bacteria are metabolically flexible, capable of dormancy, and can utilize various organic and inorganic energy sources, including atmospheric trace gases, to survive and grow. Studying these microbes diversity, ecology, and function enhances our understanding of how life persists and biodiversity is maintained in the face of climate risks such as desertification and nutrient depletion.
Theme 2
Soil Fertility & Environmental Resilience
Soil biomes are complex ecosystems rich in microbial diversity, which play a crucial role in soil productivity. These microbes facilitate nutrient cycling, decompose organic material, and support plant health. By studying the structural and functional aspects of microbial biodiversity in soils, we can gain insights into their contribution to ecosystem services. This understanding can inform strategies to improve soil health, resilience to disturbance and enhance productivity, contributing to sustainable agricultural and environmental practices.
Theme 3
Atmospheric Change
& Global Cycles
Microorganisms are essential in driving global biogeochemical cycles, encompassing carbon and various nutrient cycles. They regulate greenhouse gases like methane, carbon dioxide, and nitrous oxide, which are vital for climate regulation. Our research indicates that soil bacteria are instrumental in cycling these gases through a range of ecosystems. Understanding these microbial processes across different ecosystems and land use types is critical for devising effective climate change mitigation strategies.
