My research focuses on multiple aspects of biogeochemistry from terrestrial and oceanic C cycle to deep biosphere and paleo-climate. This includes:
- Fluvial transfer of organic carbon from continental reservoirs to the ocean.
- Impact of climate change on the dynamics of terrestrial organic carbon cycling.
- Deep biosphere, role of microbial communities in sedimentary systems.
- Carbon cycling in the Critical Zone.
- Radiocarbon dating (compound specific, ramped pyrolysis/oxidation), new dating techniques.
- Developing paleo-climate proxies, e.g. compound specific stable isotopic measurements.
- Relationships between erosion, tectonics and climate over long timescales.

Along with my colleagues from WHOI and the Woods Hole Research Center I am part of a wide initiative - the Global Rivers Observatory - and study a wide range of river systems including the Amazon, Congo, Ganges, Brahmaputra, Fraser, Mackenzie, Yangtze and Connecticut Rivers to name only a few. I also study marine sedimentary records to understand past variations of the organic carbon cycle, in particular the relationships between climate change and the dynamics of organic carbon exchange. I use a range of state of the art techniques - such as compound specific radiocarbon dating - to characterize and understand the dynamics of organic carbon exchanges during continental erosion. I use and develop organic proxies - such as compound specific stable isotopic measurements - to study paleo-climate over timescales from centuries to millions of years.Finally, I am also interested in the relationships between erosion tectonics and climate over long timescales, in partiulcar the relationships between Himalayan erosion and climate over the Cenozoic.
