The overarching theme of my research is the use of sedimentary, microfossil and geochemical indicators to produce and synthesize records of present and past storms, floods and sea levels, and their extent of geological and ecological impacts. These records provide means to assess future risk, reveal the spatial and temporal variability of coastal inundation and decipher the relationship of these events to global climatic changes. My current research interests fall into, but are not limited to, the following three broad areas of investigation: (1) local to global drivers of relative sea-level change to improve future projections; (2) the impact of extreme events (storms, floods, tsunamis) on coastal systems and evolution, and (3) quantifying processes of coastal change.
My research interests lie mostly in sedimentology, geomorphology and micropaleontology. I use microfossil, stratigraphy and geochemical proxies to reconstruct paleoenvironment and paleo-sea-level changes. My current researches focus on Quaternary sea-level history of the Greater Bay Area and to a greater extent, the South China Coast.

My research mainly focuses on using environmental DNA (eDNA) to reconstruct sea level. As a powerful ecological tool, eDNA has great potential for paleo-environmental and paleo-geological studies. I’m trying to validate the feasibility of the application of eDNA in Holocene sea-level reconstruction and to extend the sea-level record in Hong Kong using eDNA.
I am interested in studying the impact of geologic processes on global climatic change and finding ways to alleviate this issue. My PhD research involves the use of sedimentary and geochemical methods to investigate sea-level changes and carbon sequestration in coastal areas. Currently, I am focusing on Holocene sea-level changes in North China.
