Scientist

Biography

Terrestrial ecosystems are a fascinating yet poorly resolved component of the Earth’s water and carbon cycles. My primary interests are to investigate global-scale terrestrial carbon-water cycle processes and their influence on carbon exchanges between the atmosphere and the terrestrial biosphere. My interests include resolving biosphere-atmosphere carbon exchanges by synthesizing satellite-based measurements of land-surface states and fluxes and atmospheric CO2 and CH4 concentrations in an effort to advance understanding of terrestrial ecosystems. To this end, I use Bayesian paradigms to couple biogeochemical models with satellite datasets to resolve the integrated process controls and climate sensitivity terrestrial biosphere, and to ultimately advance knowledge on the role of terrestrial ecosystems in the broader Earth System.
