My research explores past, present, and future atmospheric carbon dioxide levels. I am working on explaining why atmospheric carbon dioxide levels were lower during glacial times. My research on contemporary and future carbon dioxide levels attempts to explain why atmospheric carbon dioxide levels are increasing more slowly than expected.

I have introduced the impact exsolution hypothesis to link the Chicxulub collision and the state change in Deccan volcanism. This research explains how planetary scale collisions may trigger volcanism: when large objects such as asteroids or comets hit planets, they generate seismic waves that cause exsolution in magma, which initiates eruptions. Since co-occurrences of impactor collisions and volcanism have been linked with mass extinctions, this may help improve our understanding of the events surrounding the Cretaceous-Paleogene boundary. Further, impacts may have triggered past volcanic eruptions on Earth and other planets, and may play a role in triggering future volcanic eruptions.
