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