About Yifan

Yifan got his PhD in Civil (Hydraulic) Engineering from The University of Auckland. His thesis focused on sediment scour at complex bridge piers that are widely adopted in New Zealand and many other countries worldwide. From late 2019, Yifan worked as a postdoctoral researcher at The University of Auckland and, in parallel, a civil engineer at Wellington Water to help design and plan urban water infrastructure in Greater Wellington. Before coming to Aotearoa New Zealand, Yifan graduated from Hohai University in China with BE and ME in Harbour, Coastal and Offshore Engineering. The diverse background shapes Yifan’s wide research focus and injects him with enthusiasm for research and teaching as an academic.

Yifan has a particular obsession with the motion of water and other associated physical processes, e.g. sediment transport, fluvial and coastal evolution, etc. Yifan is also a lover of Māori language and culture and a good Haka performer.

Research Interests

Currently, my research concentrates on three main aspects:

  1. Scour and erosion hazards in fluvial and marine environments. A main focal point of my existing and ongoing research is sediment scour and erosion at complex infrastructures, e.g. bridge foundations, river training structures, etc. The ultimate goal will be establishing a comprehensive scour risk model for New Zealand.
  2. Hydrodynamics and the anthropogenic influence on sediment transport. I am working with both internal and external collaborators for various projects, including turbulence around infrastructures, offshore wave dynamics, bedform mechanism, incipient bed motion using instrumented sensors, etc.
  3. Integrated management of urban water resources. I have been staying connected with both the industry and academia to resolve real-life problems of urban water governance, conservation and resilience. Typical themes include urban flood, water supply resilience, river restoration, etc. I was also involved in formulating China’s first national guideline for evaluating river/lake health.
