Research Interests

My research investigates the fate of methane released from ancient carbon stored in Arctic Ocean shelf sediments. I seek to understand the strength of source/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 I use to assess the role of ancient carbon sources in acting as a positive feedback to ongoing climate change.
