Jidu is a Postdoctoral Researcher at the University of California, Berkeley. Prior to joining Professor Soga’s group, he earned his PhD from the Hong Kong University of Science and Technology (HKUST) under the supervision of Professor Jidong Zhao (https://jzhao.people.ust.hk/). He also received both his Bachelor’s and Master’s degrees in Hydraulic Engineering from Hohai University in Nanjing, China. His current research focuses on developing new material point method (MPM) algorithms for engineering applications such as iron pipe fracturing and 3D concrete printing. In parallel, he works on multiscale thermo-hydro-mechanical (THM) modeling of granular media, with an emphasis on permafrost and methane hydrate-bearing sediments. His research interests include:

  • Efficient and stabilized MPM algorithms for coupled THM large-deformation problems in geomechanics
  • Multiscale modeling of granular materials with phase transitions (e.g., frozen and hydrate-bearing soils) using coupled MPM-DEM
  • Climate-change-related geohazards, including rainfall-induced landslides, retrogressive thaw slump, and instabilities triggered by hydrate dissociation
  • Rheology of fresh concrete and 3D concrete printing
