Research statement
My interest is mainly about fluvial damming events in geological history, to better understand of the dynamic process of fluvial landforms. Many dammed palaeo-lakes occurred during the Quaternary period, especially ice dammed palaeo-lakes. These lakes could have impounded huge volumes of water, and resulted in mega-floods. So, the damming of a river may have a significant influence on the valley landform, e.g., lacustrine, flood sediments, and bedrock erosion. By combining geomorphic investigations and geochronology, the spatio-temporal distribution of damming events and associated floods can be reconstructed. The middle Yarlung Tsangpo River on the Tibet Plateau was likely dammed by glaciers during the late Pleistocene, and I’m focussing on the Xigazê-Yueju valley. Additionally, well-preserved fossil mollusk shell record hydrochemical information of the palaeo-lake. To better understand this record, between March 2021 and March 2022, I collected modern shells and ambient water samples from southern China, to explore the relationship between them.
Biography
From September 2012, I studied geomorphology at Institute of Tibetan Plateau Research, Chinese Academy of Sciences, and got my PhD degree in the summer of 2017. I then became a lecturer at the School of Earth Sciences, East China University of Technology. To continue the study of dammed palaeo-lakes at the Yarlung Tsangpo River, a set of OSL samples was collected from two lacustrine terraces and an aeolian sequence deposit. With these samples, the age and distribution of the palaeo-lakes can be constrained. I joined the ICE group in March 2022 to realise this research project.
