Ahoyhoy, my name is R.J. Graham. I'm a DPhil student in AOPP working in Ray Pierrehumbert's group. Currently my research is focused on modeling geochemical climate feedbacks on rocky planets. I'm supported by a Clarendon Scholarship.
I use models of varying complexity to study the atmospheres and climatic evolution of Earth and hypothetical "Earth-like" exoplanets. Currently I am focused on the feedback of silicate weathering on atmospheric CO2 levels and global climate for temperate planets. I have also used GCM simulations to explore the dynamics of terrestrial planetary atmospheres during snowball events. With my research, I aim to understand the processes that initiate, maintain, threaten, and end habitability for wet, rocky worlds like Earth. How unique is our planet?
