Dr Yao Liu

Assistant Professor

Department: Geography and Environmental Sciences

The role of time is central for understanding climate change impacts on our ecosystems. A primary theme of my research is “ecological memory” – How do past environmental and biological conditions shape the current behaviour of an ecological system? To answer this, I study the temporal dynamics and memory effects in systems spanning a range of time scales:

  • Photosynthesis in fluctuating environments
  • Tree growth
  • Ecosystem carbon fluxes
  • Ecosystem (particularly forest) origination, transformation, and resilience

I specialise in Bayesian data analysis, and my research often combines observational, experimental, and modelling approaches. For example, I am using chlorophyll fluorescence monitoring, manipulative experiments on plant mutants, and data-driven dynamical system models to understand the memory of non-photochemical quenching and how its various components work together in fluctuating environments.
