The focus of our research efforts lies in the development of creative solutions to geotechnical engineering challenges that stem from the characteristic performance levels of soils in their natural state.
In classical geotechnical engineering areas, performance is most often defined in terms of mechanical properties such as strength and stiffness. While soil improvement in these areas is already a mature field, modern sustainability challenges force us to revisit conventional methods used to engineer geomaterials. Through improved understanding of soil behavior, we work to optimize the use of available improvement methods that carry low sustainability ratings, while also identifying suitable sustainable alternatives. Our interest in classical problems is also driven by our desire to bridge the gap between the state of the art and the state of the practice.
In contemporary geo-challenges, performance is defined in a variety of forms and often involves intricate relationships between mechanical, thermal, hydraulic, and biological properties. Such modern challenges encompass coupled phenomena that create the need for engineered geomaterials capable of fulfilling multiple roles simultaneously. Our work in these areas is in many aspects pioneering in the field of geotechnical engineering, but borrows heavily from the vast available knowledge in physics, chemistry, and biology.
