Brief Introduction

I'm a physical geographer with considerable research and teaching experiences in fluvial geomorphology. My research mainly focus on fluvial (riverine) sediment in large Asian rivers such as Yellow River, Yangtze River, and Mekong River etc. I have also research experience on carbon cycles in waterbodies (rivers, lakes and reservoirs). I jointly organized a series of workshops on large Asian rivers and involved in publishing 10 special volumes as one of the Guest Editors on large Asian rivers in Quaternary International. 

I have widely published in the field of fluvial geomorphology in high quality journals,  including in Science, Nature Geosciences,  and Nature Reviews Earth & Environment.  My publications are widely cited, including three highly cited papers.  I have a total citation of over 9500 (exclusive self-citation) and H-index 58, as of July 2023, in Web of Science.  

I have successfully supervised a dozen of PhD students, including award winners like Zhang Shurong (Chinese Government Award for Outstanding Self-financed Students Abroad in 2006), Wang Jianjun (World Future Foundation PhD Prize in Environmental and Sustainability Research in 2009),  Li Dongfeng (IPCC Scholarship Award in 2029; Wang Gungwu Medal and Prize in 2022, Chinese Government Award for Outstanding Self-financed Students Abroad in 2006), Zhang Ting (IPCC Scholarship Award in 2023).

I'm currently a co-editor of Singapore Journal of Tropical Geography, an associate editor of International Journal of Sediment Research, and Hydrological Processes,  and an editorial board member of Earth Surface Processes and Landforms.

 


Teaching Areas

I taught various modules in the past at undergraduate level, GE1102 Global Environments, GE1101E/GEM1001K: Place, Environment and Society, GE2018/SSA2215: The Biophysical Environments of Singapore, GE2215: Introduction to GIS and remote sensing, GE2220 Environmental Processes: Terrestrial and Coastal, GE3221 Ecological Systems, GE4211 Advanced Hydrology and Water Resources Management,  and at graduate level,  GE5220 Selected Topics in Geography I, GE6220 Selected Topics in Geography II, GE6215 Current Issues in Environmental Sciences, GE6211 Spatial Data Processing.

I currently focus for my teaching on GE3256 Earth Surfcae Processes, Landforms and Ecosystems and GE4222 Advanced Geomorphology. 


Graduate Supervision

I'm interested to work with postgraduate students on riverine sediment and carbon fluxes, and Greenhouse Gases Emiission (GHGs) from water bodies. Many students under my supervision have sucessfully graduated and landed a good job, Joy Sanyal, Li Luqian, Zhu Yunmei, Huang Jingnan, Desmond Lee, Zhang Shurong, Emlyn Hagen, Wang Jianjun, Ran Lishan, Yang Xiankun, Han Hongjuan, Liu Shaoda, Lin Lin, Sastry, Li Dongfeng, Zhang Ting.

 

 

 


Current Research

I'm currently working on the projects listed below:

  • Sediment fluxes from the headwater regions of large Asian rivers
  • Carbon fluxes and carbon emission from large Asian rivers
  • Impacts of eutrophication on GHGs emission
  • Dams and the Mekong River changes 

Research Interests

My research seeks to understand riverine sediment and its associated carbon fluxes, burial and emission (or outgassing or evasion) which are an important part of carbon exchange between terrestrial, oceanic and atmospheric environments and thus must be considered in strategies to mitigate climate change. However, understanding of spatial and temporal dynamics of such exchanges is very limited for the large Asian rivers that originate from the Himalaya mountains and Tibet Plateau.

I'm particularly interested in the topics listed below:


- Quantification of sediment/carbon fluxes and carbon burial/outgassing from large Asian rivers
- Impacts of dams construction and land use change on sediment fluxes and carbon cycles
- Impacts of climate change and resultant glacial retreat or permafrost thawing on sediment/carbon fluxes in the headwater region in Tibet Plateau
