Most of my current research focus on constraining past ice sheet variation and it induced solid earth deformation and global sea-level change from ~35,000 years ago to present. To achieve this I am using the glalcio-isostatic adjustment model, see an example output global ice sheet & sea-level change pattern on the right side. Because ice sheets and sea level are sensitive to the global climate change, understanding how past ice sheet response to global climate change plays a key role to understand the global climate variability from past to future.

Fingerpringting meltwater pulse events

Rising sea levels due to warming climate pose a great risk to society, improving our understand of why and how fast change could happen will help us plan for the impacts. Rapid sea-level rise has happened in the past (meltwater pulse events), and studying such events provides vital clues. To understand the interactions between fast freshwater discharge from melting ice sheet and global oceanic circulation, a fundamental question is to find how much each ice sheet contribute to a specific meltwater pulse event. I have developed an algorism to robustly find our the sources for any meltwater pulse events ustilising a technique so-called ‘sea-level fingerprinting‘ (which describes how global sea-level change corresponding to ice melt from a specific source, see an example of Antarctic ice sheet on the left) and geological sea-level records.
