Northwestern University undergraduate researcher Ben Levinson (left) watches postdoctoral researcher Rama Balasubramanian adjust the levels of air and methane flow in a fermenter. The air and gas flow must be monitored all day to ensure optimal conditions for growing methane-oxidizing bacteria.

Professor Amy Rosenzweig of Northwestern University seeks to understand methane-consuming bacteria, known as methanotrophs, and how they leech copper out of the environment. The potential applications for this work include scrubbing methane, which is a potent greenhouse gas, from the atmosphere, as well as removing toxic heavy metals from soil and water.
