Motto

Imagination is more important than knowledge

Albert Einstein

Our research group values the integration of science and technology from multiple disciplines to address the infrastructure challenges. This generally requires knowledge from different areas, but more importantly, it requires “out-of-the-box” ideas and imaginations.

We borrow Einstein’s energy equation to explain how to achieve great things:

E=mc², where E is “Excellence”, m is “motivation”, c² is “creativity” by “critical thinking”

RESEARCH STATEMENT

We have keen interests in exploring fundamental mechanisms of and innovative countermeasures to emerging infrastructure challenges, particularly in the broad area of smart, sustainable and resilient geotechnical engineering. Our research is highly interdisciplinary including high-definition numerical modeling of interactions between particulate materials and flow, experimental development and characterization of bio-inspired and smart materials, development and application of bio-inspired infrastructure design and etc.
