Dr. Tadahiro Kishida holds a PhD from the University of California, Davis (USA). He was an Assistant Project Scientist at the University of California, Berkeley (USA); Assistant Professor at Chiba University (Japan); Engineer at URS Corporation in Oakland, California (USA). He is a visiting scholar at the University of California, Los Angeles (USA). He holds a professional engineering license in the State of California. He was awarded with Faculty Research Excellence in 2018 and 2019.
Sustainable ballast design for railway system using locally available natural and recycled materials
The project conducts the static and dynamic tests for recycle aggregates and evaluates their performance. Constitutive models are developed under low confining stress with high repeated loading.

Updating Seismic Hazard Assessment in the UAE
The project revises the seismic hazard assessment for the UAE, incorporating the latest data and insights to align with the Abu Dhabi International Building Code (ADIBC).
Improving Calcareous Reclaimed Land by Microbially Induced Carbonate Precipitation
Static and dynamic responses are studied for calcareous sand. Liquefaction potential is studied from cone penetration resistance.

Recycling Demolished Concrete for Construction Materials
The recycling of demolished concrete is examined by inducing calcium carbonate cementation between the aggregates. Mechanical responses are evaluated through both laboratory tests and numerical simulations, aligned with the certification scheme set by the Government of Abu Dhabi.
