Personal profile

Research interests

I am interested in using climate models to identify and understand feedbacks in the climate system and determine how these might be influenced by different climate states. Currently my research is focused on reconstructing and analysing climate over the Quaternary period, particularly focusing on the Last Glacial Period and Holocene. My interests are broad, covering the role of the terrestrial biosphere, atmospheric dynamics, and the impact of changing ocean circulation, particularly the AMOC. I am also interested in exploring the dynamics of how climate models work, particularly the generation and implication of stochastic variability in models, and the benefits of resolution. 

I am currently employed as a research associate investigating the drivers of the increase in carbon dioxide over the past glacial period (21kyr-10kyr), with a particular focus on changing ocean circulation. I am using the HadCM3 coupled climate model and the GENIE biogeochemical model. My previous research has particularly focused on the feedbacks between CO2 and the land surface with the Atlantic Meridional Overturning Circulation (AMOC), an important system of North Atlantic Ocean currents that strongly influences climate in Western Europe and beyond.
