Resume:

2022.04–present Associate professor, Guangzhou Institute of Geochemistry, CAS

2019.07–2022.03 Postdoctoral researcher, Guangzhou Institute of Geochemistry, CAS

2014.09–2019.05 Ph.D. in Quaternary Geology, Royal Holloway University of London

2012.09–2019.09 Ph.D. in Geochemistry, Guangzhou Institute of Geochemistry, CAS

2008.09–2012.06 B.Sc. in Geology, Sun Yat-Sen University

Research Interests：

Tephrochronology, tephrostratigraphy, explosive volcanic eruptions, Bayesian age modeling. I specialize in the identification of non-visible volcanic ash (cryptotephra) deposits from various sedimentary archives and the use of tephra layers to date and synchronize paleoenvironmental records. My recent research interests focus on (1) the use of cryptotephra methods to refine the eruptive history of Asian volcanoes, (2) the use of Bayesian modelling techniques to improve age models of sedimentary archives and (3) the construction of regional tephrostratigraphic frameworks in East Asia and the wider Asian region.
