In our second episode with natural hazards engineer Jason DeJong, we learn about biogeotechnics — a field that links biology and the natural world with engineering. DeJong explains how researchers at NHERI UC Davis have learned to use bacteria to chemically bind sand particles and create high-strength soils — that are resistant to liquefaction. It’s called biomediated ground improvement. A related approach, called biomimicry or bioinspired engineering, seeks to imitate natural designs. For example, engineers at UC Davis study snake skin to design more efficient piles.“How can we push more towards bio systems that can be that much more efficient.”
