Welcome. We trust that you will find this site informative and helpful in your "googling" searches. It is designed to provide snapshots of our activities, so if you find something of interest feel free to contact one of us for more information. We'd be interested in conversing with you further.

On the research side, we primarily focus on a suite of topics related to the interaction of soil with various processes including biological activity, structural element interfaces, and in situ probes and sensors. Our approach stems from fundamental science-based inquiry of processes, mechanisms, phenomena, and then leveraging this understanding to provide solutions to practical engineering problems. Often this occurs in a collaborative interdisciplinary and international research environment.

Recently we have invested our energy heavily in bio-soil interactions on two fronts: research in the laboratory and organizing a US-UK bio-soils research initiative. In the laboratory we are working to harness natural biologic activity to stabilize soils. One example of this is transforming transform loose unstable sands into sandstone. We, with our UK colleagues, are leading efforts to guide and coordinate research in this new emerging discipline. This effort was launched in April 2007 through an international workshop funded by the National Science Foundation (US) and the Engineering and Physical Sciences Research Council (UK).

On the education side, we've made available various resources that we have collaborated in the development of, including an educational video and a site investigation manual (see Resources). We are now implementing an integrated Personal Response System (PRS) – Tablet PC platform in undergraduate classes to enhance student comprehension and learning. Feedback from students confirms material comprehension and understanding is improved relative to traditional chalk and talk lectures.

We endeavor to make graduate studies a full experience - where research that advances society is accomplished while students are mentored and develop the necessary technical and life skills for life-long careers and societal contributions. This experience typically includes presentations, site visits, travel to conferences, collaboration with other disciplines, and international and/or national travel for research.
