Atmospheric greenhouse gases provide the largest anthropogenic climate forcing. The concentration of CO2 and other greenhouse gases will change over the next century, due to both human activity and feedbacks in the carbon cycle. In particular, feedbacks between climate and terrestrial ecosystem carbon storage will have large effects on the atmospheric composition and hence radiative forcing.

Our research group uses atmospheric and remote sensing observations to develop an understanding of processes that govern the exchange of carbon among reservoirs in the atmosphere, oceans, and terrestrial ecosystems. We employ observations to test and improve process-based models ranging in complexity from simple box models to Earth System Models.

I am always interested in hearing from bright, motivated students at the undergraduate and graduate level. Please email me if you are interested in carbon cycle science at UM.
