GAGE promotes fundamental research in the development and application of analytical methods that reveal past and present changes in Earth's climate, its land surface, and major biogeochemical cycles.
Center members have expertise in marine and isotope geochemistry, biogeochemistry, and geochronology, which are combined with geomorphology, Quaternary stratigraphy and ecosystem ecology to address scientific questions of recognized importance.
GAGE faculty capitalize on the rapidly advancing tools in geochemistry to more accurately characterize changes in Earth’s environments.
Faculty
Research foci
Key topics include:
- Isotopic and molecular approaches to understanding the modern carbon cycle
- Quantitative reconstruction of past environmental changes to reveal links between components of the global climate system
- Documenting the processes in the geomorphic system that result in large-scale landscape evolution and the rates at which those processes act.
Student participation
The active participation of graduate and undergraduate students is encouraged and ensured through formal course offerings, the development of the Carbon, Climate and Society Initiative IGERT program for graduate education, and access to specialized research facilities and employment opportunities.
