Perspectives
Commentary, insights, and public engagement on geotechnical engineering and sustainability
The ground beneath our cities holds answers that the world has not yet thought to ask for.
Geotechnical engineering sits at the intersection of climate response, urban resilience, and the clean energy transition. Yet it rarely commands the public or policy attention it deserves. I write and speak to change that - translating rigorous science into accessible insights for industry, policymakers, and the public.
The underground is the defining infrastructure of the next century. The sooner that is understood, the faster we move.

A Vision for a Stronger Global ISSMGE
As President of the International Society for Soil Mechanics and Geotechnical Engineering, I have outlined seven strategic pillars to modernise the Society, expand its global reach, and strengthen its impact.
- Champion sustainability and climate action across the profession
- Build a global educational platform for geotechnical engineers
- Modernise governance and increase transparency
- Strengthen regional society engagement and inclusion
- Promote innovation and technology transfer
- Expand the Society's voice in public policy
- Develop the next generation of geotechnical leaders
"The most important advances in geotechnical engineering will not come from incremental refinement. They will come from those willing to reimagine what the ground can do - not merely as a foundation, but as an energy source, a carbon repository, a living material."Lyesse Laloui
