Ezra is currently a Ph.D candidate in Civil and Environmental Engineering Department of University of California, Berkeley. He obtained his B.Eng in 2014 from the Hong Kong University of Science and Technology (HKUST) and M.S. in 2016 from University of California, Berkeley. Upon his graduation from HKUST, he worked at Arup Hong Kong on jobs including 27 m excavation at Repulse Bay and preservation of historical retaining walls at Central area. In the Bay Area, he has worked at Rockridge Geotechnical on jobs including ground improvements using drill displacement column, and earthquake retrofitting and seismic upgrades.

In the scope of the PhD, Ezra is focusing on developing Material Point Method code with CB-GEO with applications of 3D landslides and dam failure. Here are some early simulation results of a debris flow in Hong Kong and a dam failure in California.

🔬 Research Interests:

  • Numerical model
  • Material Point Method (MPM)
  • Debris flow
  • Constitutive model of sand (static and cyclic)
  • Dynamic soil liquefaction
