Research Interests

My research investigates the fate of methane released from ancient carbon stored in Arctic Ocean shelf sediments. We investigate the strength of source and sink processes that determine how much methane is emitted from shelf hydrates and permafrost to the atmosphere. Natural abundance radiocarbon and stable isotope measurements of methane are the primary tools we use to assess the role of ancient carbon sources in acting as a positive feedback to ongoing climate change.
