Research Statement

I am interested in interdisciplinary research in terrestrial ecosystem ecology, biogeochemistry, soil-plant-atmosphere interactions, and global change ecology. My research focuses on studying the climate change impact on ecosystem processes and functions, and the feedback of terrestrial ecosystems to climate change. Specifically, I use observational, experimental, and modeling approaches to understand and simulate carbon, nutrient, and water cycles within ecosystems and between ecosystems and the atmosphere across various scales. My research improves our understanding of future changes in ecosystem dynamics, productivity, and biodiversity. My research can be applied to evaluate carbon sequestration and management, and ecosystem service and management.

I have been studying various ecosystems, from Mediterranean-type forests and savanna grassland in the Sierra Nevada of California to northern forests and prairie grassland in the Midwest, and recently to temperate forests in New England and tundra ecosystems in the Arctic. Currently my research focuses on 1) soil respiration and its partitioning into microbial and root respiration, respiration-photosynthesis interaction, and warming effects on belowground processes in a temperate forest at Harvard Forest in New England; 2) effects of warming and changes in seasonality on soil carbon fluxes and belowground processes in tundra ecosystems in northern Alaska; 3) effects of climate change on phenology and carbon cycles in oak forests on the Island of Martha’s Vineyard in Massachusetts, and 4) greenhouse gas (CO2, CH4, N2O) emissions of agricultural systems and their responses to fertilization and other management practices.

You are welcome to contact me if you are interested in the graduate program at Brown University through the Brown-MBL program, or in an undergraduate internship, Undergraduate Summer Research (REU) Program at Harvard Forest at Harvard University, or research positions such as postdocs, research assistants, or visiting scholars.
