Sharon Gourdji
Postdoctoral Fellow

Research Interests:
Carbon dioxide flux estimation:  Using geostatistical inverse modeling to estimate carbon sources and sinks at global and regional (North America) scales.  Attributing components of CO2 flux to various processes (photosynthesis, respiration, biomass burning, fossil fuels, etc.).
Climate change policy: How to better integrate scientific knowledge production into the policy-making process, specifically in the field of climate change mitigation and adaptation.

Deborah Huntzinger, Ph.D.
Postdoctoral fellow

Research interests:
Comparison of "bottom-up" and "top-down" estimates of carbon flux in North America, including the examination of the spatial variability and uncertainty in flux estimates obtained from existing biospheric models.

Kim Mueller
Postdoctoral Fellow

Research Interests:
My research interests are focused on using geostatistical techniques to evaluate biospheric and climatic influences on carbon dioxide fluxes to further the general knowledge of the carbon cycle and to assist terrestrial carbon budgeting.  Geostatistical techniques include kriging with a variable trend using CO2 eddy flux measurements and inversion that couples atmospheric concentration data with an atmospheric transport model.  Both techniques allow for the inclusion of various climatic and/or vegetative variables.  As such, it is possible to study relationships between climatic or vegetative variables and carbon dioxide flux at various spatio-temporal scales as seen by the measurement information.  As part of NSF's Biosphere Atmosphere Research & Training (BART) IGERT program, my research uses data from the University of Michigan Biological Station Flux Tower Site in northern lower Michigan.  Inverse modeling will be part of a project funded through the NASA North American Carbon Program as well as the BART fellowship.

Vineet Yadav, Ph.D.
Postdoctoral fellow

Research Interests:
My academic focus lies at the intersection of carbon dynamics, land cover and climate change. Methodologically, I employ remote sensing, GIS and statistical modeling to investigate my research problems.  In the past, I have concentrated on research projects on biospheric modeling of historical soil organic carbon transformations and developing a decision support database for "cap and trade" agricultural C market systems. Presently, as a  post-doctoral fellow I am involved in a NASA-funded North American Carbon Program project.  Under the aegis of this project, I am contributing in improving understanding of the spatial and temporal variations of the North American carbon fluxes at multiple scales.

Dorit Hammerling
Ph.D. Candidate

Research Interests:
My general research interests are statistical methods that can be applied to improve our knowledge of geophysical phenomena and to solve environmental problems.  I am specifically interested in spatial and spatio-temporal statistical methods for large satellite data sets.  My thesis research is focused on gaining better insights in the functioning of the carbon cycle by deriving global atmospheric CO2 concentrations from satellite measurements.

Dan Obenour
Ph.D. Pre-candidate
School of Natural Resources and Environment

Research Interests:
My research interests lie in the development of models that improve our ability to understand and manage complex environmental systems.  I am particularly interested in surface water quality, and my current research is focused on the hypoxic zone in the northern Gulf of Mexico.  Methodologically, I am interested in using geostatistics to model the spatial and temporal variability of Gulf hypoxia, and to evaluate factors related to its formation.  I am also interested in exploring how a biophysical model can be integrated within the geostatistical modeling framework to enhance its predictive capabilities.
