Ha Bui received his PhD degree in Civil Engineering from the School of Science and Engineering Ritsumeikan University, Japan. He then worked as a Research Fellow at the Department of Civil Engineering at Ritsumeikan University. His research focused on developing advanced numerical methods and constitutive models for large deformation and flow failure predictions of geomaterials.
