Aquatic microbiology and ecosystem ecology


I am a microbial ecologist and aquatic scientist interested in how ecosystems function. Bacteria are the most abundant and diverse organisms on the planet and most aspects of energy flow in ecological systems are somehow regulated by their metabolism. We know so little about the ecology of environmental microorganisms like Bacteria that we cannot yet fully incorporate the microbial world into our understanding of how ecosystems function and how they are changing worldwide. My research broadly aims to examine the role of this "unseen majority" in the environment and understand the basic ecology, assembly, and persistence of these hyper-diverse communities.
