Our mission is to conduct cutting-edge, interdisciplinary, collaborative research to advance ecosystem ecology and biogeochemistry with new theories, tools, and methods; and to apply our findings to conserve, restore, and manage ecosystems and their services under the context of climate change and human influence.

Our research goals are to advance our understanding of ecosystem processes, biogeochemical cycles, soil-plant-atmosphere interactions, and their impact from and feedback to climate change. We develop novel tools with observational, experimental, and modeling approaches to enhance our ability to quantitatively describe and simulate greenhouse gas (CO2, CH4, and N2O) emissions, carbon and nitrogen cycles, and their linkage with ecosystem phenology. We study a variety of ecosystems including temperate forests, agro-ecosystems, coastal salt marsh, and Arctic tundra.

The ongoing projects include

  1. Greenhouse gas emissions and carbon sequestration (blue carbon) in response to climate change and human management in coastal wetlands.
  2. Arctic ecotypes and climate change.
  3. Phenology, fluorescence, and carbon cycling.
  4. Abiotic and biotic controls of soil respiration and soil carbon dynamics.
  5. Greenhouse gas emissions from agro-ecosystems and their responses to fertilization and management.
  6. Synthesis/synergistic activities.
