I am generally interested in the potential for carbon sequestration in soil to mitigate climate change. My research includes modelling potential warming reduction from global scale improvements in agricultural land management, modelling the effect of compost application to soil organic carbon in California grasslands. I am currently working at both UC Berkeley and at the Center for Accelerator Mass Spectrometry at Lawrence Livermore National Lab. At CAMS, I am measuring radiocarbon to analyze changes in soil carbon storage and turnover over three decades in the Luquillo Experimental Forest in Puerto Rico.
