Overview
My research focus is on understanding the ecology of microbes through examination of their genes and lifestyles. Bacteria are the most diverse organisms on earth and play a pivotal role in planetary cycling of nutrients and energy. Yet, we have a poor understanding of the factors that drive their diversity and dynamics in the environment. The lab's emphasis is on studying bacterial interactions with the environment at the appropriate temporal and spatial scale including the effect of temperature changes on bacterial populations and bacterial interactions with other organisms. Another area of active research is the response and adaptation of bacteria to emerging pollutants such as antibiotics and nanoparticles.
