Ritwika is looking into reconstructing Early Cretaceous continental climate through d18O as a proxy for precipitation and temperature, and linking this to changes within the global carbon cycle. She is also interested in comparing greenhouse and icehouse continental climate through time, particularly using similar proxies.

Henry is interested in the formulation of present duties toward people of future centuries in light of the fact that we may now lock-in irreversibly disasters (like extreme sea-level rises) that will not occur until centuries later.
Rebecca is interested in the use of cryptotephra (volcanic ash) in order to gain an improved understanding of how the magnitude and frequency of past volcanic eruptions have changed through time, the causal mechanisms that may have influenced these changes and the use of tephra as isochronous marker horizons in order to improve chronological precision.
