Tengwen was trained as a Quaternary scientist and his research focuses on the human dimensions of past environmental change. He has a broad interest in recent or distant past of the Earth and social systems, but in particular specialises in reconstructing long-term interactions between human societies and environment in China using palaeoecological and geochronological techniques. His publications were highlighted in top journals and social media, including Nature Plants and Science Advances.

Before joining UNNC, Tengwen had his PhD from Trinity College, the University of Dublin, and worked as a postdoctoral scientist at Freie Universität Berlin and German Archaeological Institute.

Tengwen is always happy to collaborate in the broad field of environmental change and welcomes highly motivated students to discuss potential research projects. Please contact him for further information.

Expertise Summary

Tengwen specialises in using sediment-based techniques to reconstruct past environmental change on a range of timescales, especially in techniques from palaeoecology and 14C chronology.


Tengwen teaches Principles of Ecology (GEOG1022) and Techniques in Environmental Science (GEOG2050). He convenes Dissertation Preparation (GEOG2043) and Dissertation (GEOG3046).
