Jidu is a Ph.D. student in Geotechnical Engineering at the Hong Kong University of Science and Technology (HKUST) and is a visiting researcher at the University of California, Berkeley. His Ph.D. thesis supervisor is Prof. Jidong Zhao (https://jzhao.people.ust.hk/). Before joining Prof Zhao’s Computational Granular Mechanics Lab, he obtained both his Bachelor’s and Master’s degrees in Hydraulic Engineering from Hohai University in Nanjing, China. He is currently working on thermo-hydro-mechanical (THM) modeling of granular media using the material point method (MPM), particularly for modeling permafrost and methane hydrate-bearing sediments. His research interests include:

  • Efficient and stabilized MPM algorithms for modeling thermo-hydro-mechanical coupled large deformation problems in geomechanics.
  • Multiscale modeling of multiphase granular materials with phase transition (e.g., frozen soils and hydrate-bearing soils) using MPM-DEM.
  • Geohazards related to climate change, e.g., rainfall-induced landslides, permafrost thaw-related problems, and hydrate dissociation-triggered instabilities.
