I am a biogeochemist interested in nutrient and energy dynamics in the plant-microbe-soil complex. Specifically, I focus on how plants and soil microbes interact in response to disturbances and external environmental changes. I completed my Ph. D. in Natural Resources at University of Idaho in 2007. I started working at CSU in 2011. Since then, I have been involved in various projects, including the Biotic Awakening project in Arctic tundra ecosystems at Toolik, Alaska, Boston Area Climate Experiment (BACE), Prairie Heating and CO2 Enrichment (PHACE) and Great Plains Methane Project. I am experienced in a suite of methods to elucidate biogeochemical processes and microbial structures in soils, including extracellular enzyme assays, microbial metagenomics, greenhouse gas measurements, and use of stable isotopes. I am especially excited about recent development and potential of high-throughput sequencing (e.g. 454 Roche and Illumina) which can be applied for microbial metagenomics. I want to pursue high-throughput sequencing to assess soil microbial structures which can shape ecosystem function.
