Alison Marklein is a quantitative biogeochemist who focuses on the effects of soil chemistry, climate change, agricultural management on soil carbon storage and plant growth. Her past research has focused on how interactions between nitrogen and phosphorus affect terrestrial carbon sequestration and the dynamics of plants and microbes. She received her B.A. in Computational Biology at Cornell University in 2008 and her Ph.D. in Ecosystem Biogeochemistry at UC Davis in 2014. She worked as a postdoc at UC Davis and the University of Montana before joining LBNL in 2016.
