A recent Roane State Community College graduate is researching climate change and the microorganisms that contribute to it.

Rachel Andrews, a Morgan County resident who graduated from the community college in May 2019, is an intern at Oak Ridge National Laboratory. She’s doing research with Christopher Schadt in the Biosciences Division at the lab.

They are investigating methane production in peat, which is formed by the partial decomposition of plants in wet, acidic conditions of bogs. Scientists say methane gas is one of the major contributors to a warming planet.

“We study the methanogens that live in peatland soil,” Andrews said in an emailed response to questions about her research. She said these microorganisms produce quite a bit of methane and carbon dioxide, also identified as a culprit in climate change.
