Aquatic Microbial Ecology and Evolution
Microorganisms are a diverse component of aquatic ecosystems and their metabolic activities are central to energy, carbon, and nutrient cycling. Our research investigates the biodiversity, metabolic versatility, and evolution of these important aquatic microbes using novel genomics-based molecular approaches. Aquatic ecosystems under investigation include northern oceans, estuaries, and seasonally ice-covered northern lakes. All these ecosystems are impacted by climate change and other anthropogenic perturbations to varying degrees. Our research is coordinated to provide insights into how microbial distributions and activities may be influenced by these environmental pressures, and how changes in microbial distributions and activities may affect aquatic ecosystems as a whole.
