Nick Ward and Matt Norwood, biogeochemists, explore greenhouse gas cycling, focusing on methane, a potent greenhouse gas with significant warming potential. They study methane emissions from trees, a recently discovered phenomenon, using portable instruments and tree core analysis. Their research includes identifying microbial activity in wood that produces methane, using tools like resistance drills and genomic analysis in labs.
