Geotechnical faculty

Ensuring a strong foundation to build on

Our faculty are experts in the behavior and structural interconnected properties between soil, rock, concrete and other man-made materials with research focusing on soil behavior, ground improvement, environmental effects in pavement design, bio-geotechnical engineering, geotechnical earthquake engineering, sustainable geotechnics, interdisciplinary geotechnics, waste containment system design and mechanical properties of municipal solid waste.

Our researchers also focus on development of sustainable nature-based solutions to mitigate risks associated with soil systems in civil infrastructure and agriculture, bio-inspired burrowing mechanisms and geosystems, smart, sustainable geosystems, material behavior, fatigue and damage in engineering structures, as well as infrastructural design and behavior under transportation, environmental and other dynamic loads in geotechnical engineering,

Faculty also are known for their research in engineering education, engineering geology, geotechnical and geo-environmental engineering, environmental biotechnology, construction microbial biotechnology, engineered living systems and materials, fungi-mediated and fungi-inspired technologies, soil erosion mitigation and interdisciplinary nature-based engineering.
