Personal Profile

Current position: Peking University / Personal Profile

I am an Tenure Track Assistant Professor in the School of Earth and Space Sciences at Peking University.


My research interests span a wide range of topics in Earth history, which I pursue through data collection, analysis and modeling. Three interrelated fundamental problems are most attractive to me:


(1) the cause of rapid and large fluctuations in sea-level during greenhouse times when there were no ice sheets on Earth;

(2) the development of geologic time scales from the record of paleoclimate change; and

(3) global climate sensitivity to forcing mechanisms in greenhouse versus icehouse times.

I have developed a novel sedimentary noise model for tracking sea-level change in marine stratigraphy, leading to evidence that groundwater has had a major impact on global sea-level change. I am involved in improving the geologic time scale with astronomically forced cyclostratigraphy. Some of my results for the Triassic time scale were adopted as global references in the Concise Geologic Time Scale 2020. Most recently, my work on data assimilation combines paleoclimate proxies with Earth system models for dynamically linked space-time reconstructions of the Paleocene–Eocene Thermal Maximum.


My teaching interests are focused on stratigraphy, paleoclimatology and quantitative time series methods to help students develop critical thinking and problem-solving skills to understand the Earth system. For this purpose, I recently developed Acycle, a time series analysis package for paleoclimate research and education.
