Research Interests: I study the responses of terrestrial ecosystems to climate variability and change. I am interested in a wide range of ecosystem types and consider time scales from the diel to the multi-decadal. My usual approach employs numerical models to evaluate ideas related to ecosystem functioning.

Research Interests: Rain and its variability play a crucial role in ecosystem dynamics, adaptation and human survival. Interestingly, different types of heterogeneities, natural or manmade, on the land surface can influence regional to large scale precipitation. My research interests lie in understanding this land-atmosphere coupling at various spatial and temporal scales and the causal physical mechanisms behind it. During my PhD I studied this regional coupling and associated precipitation change in the deforested regions of the Amazon rain forest. In the near future I will be looking at regional surface-atmosphere coupling under climate change in various other parts of the world. Through my research I want to understand the sensitivity of these regions to human induced climate change and the driving mechanisms.

Research Interests: I am interested in how ecosystems respond to climate change from local to global scales and the implications that this has for the terrestrial carbon cycle. My research focuses on integrating field measurements with numerical models to gain new insight into climate-vegetation interactions. For my Ph.D. research, I have developed a version of the Ecosystem Demography model 2 (ED2) for the North American boreal forest. I currently use ED2 in conjunction with forest inventory, eddy flux, and chronosequence measurements to assess boreal forest growth and soil carbon response to changing climate and fire regimes.
