Tengwen has a broad interest in using sediment-based methods to understand past environmental change and human-environment interactions. Initially he was trained (through an MSc in Shaanxi Normal University, China) as a fluvial geomorphologist with specialism in reconstructing Holocene palaeoflood history in the Yellow River basin. He expanded his skillset to micropalaeontology through completing his PhD in Trinity College Dublin (TCD), the University of Dublin, Ireland, having developed expertise in analysing Quaternary pollen and spores, diatoms, and phytoliths. His PhD project focused on Holocene human-environment interactions on the southern Yangtze Delta in China, notably environmental context for the origin and development of rice-based agriculture in this global centre for rice domestication. He is keen to use his skills in microfossil analysis to further explore the intriguing relationships between prehistoric societies, their domesticated plants, and environments, currently carrying out a postdoctoral project in relation to early history of hemp (Cannabis spp.) -- a versatile plant used widely in textile production, medicine, and religious rituals by prehistoric and historic societies. This interdisciplinary project is jointly hosted by Eurasia Department of the German Archaeological Institute (host: Prof. Mayke Wagner) and Institute of Geological Sciences at Free University of Berlin (host: Prof. Pavel Tarasov). Tengwen also holds a one-year research fellowship from Fritz Thyssen Foundation. Tengwen’s research experience further extends to areas such as loess stratigraphy in China, palaeopedology, and application of GIS in geomorphology. With a completed PGDip in Statistics from TCD, he is also interested in applying statistical methods to large and complex Earth science datasets.
