My major research focus is on understanding the processes involved in regulating variation and predictability of the global carbon cycle and climate in the context of the Earth system. I am using large ensemble simulations based on the Earth system model to disentangle the internal variability from the variability generated by anthropogenic perturbations. In the meanwhile, I pursue to improve the near-term predictions of ocean carbon uptake and relevant processes by initializing the Earth system model with observations and by improving the representation of mesoscale processes with high-resolution models.
