Mike C. Rowley is a postdoctoral researcher at the Energy Geosciences Division of Lawrence Berkeley National Laboratory. He is a soil biogeochemist by training and has investigated soil chemistry around the World. For his MSc. (Res.), Mike investigated the oxalate-carbonate pathway in Haiti and Mexico, a process through which oxalate-producing trees, oxalotrophic bacteria, and fungi sequester atmospheric carbon as calcium carbonate in the soil. Mike then completed his PhD. at the University of Lausanne, Switzerland. His thesis focused on investigating the mechanisms through which calcium contributes to an accumulation of soil organic carbon at the Nant Valley, Switzerland. Here at LBNL, Mike is now furthering this research topic, investigating the processes through which calcium complexes soil organic carbon. Mike’s project is jointly funded by LBNL and a Swiss National Science Foundation fellowship.
