I am an Assistant Professor in the Department of Geography at Indiana University. My research addresses policy-relevant scientific questions related to the terrestrial biosphere’s response to climate change, rising CO2, and human activity (e.g. land use/cover change and management). I have considerable expertise in using a wide range of in situ and satellite datasets within a data assimilation framework to test, develop, and constrain land surface model (LSM) vegetation and carbon cycle-related processes and parametric uncertainty. My work also includes studies investigating the impact of uncertainties in land cover maps on LSM carbon, water and energy budget estimates – a critical issue given that land cover and land use change is the second largest source of anthropogenic atmospheric CO2emissions. Given some my past work has highlighted the need to improve LSM representation of moisture-limited ecosystem processes, a recent focus of mine is on better understanding moisture controls on vegetation, water, and carbon cycle fluxes in semi-arid dryland ecosystems,
Prior to joining Indiana University, I was a Postdoctoral Research Scientist at the Laboratoire des Sciences du Climat et de l’Environnement (LSCE) in Paris, France, and a Research Associate in the School of Natural Resources and the Environment at the University of Arizona. I completed my Bachelor’s and Master’s degrees in Earth Sciences at the University of Oxford, before earning my PhD in Land Surface Modeling and Remote Sensing in the Department of Geography at University College London.
In addition to being on the AIMES Scientific Steering Committee, I am a member of the NASA CEOS Land Product Validation Biomass Focus Area Subgroup.
