Our group at the University of Minnesota focuses on fundamental advances in numerical algorithms, and understanding of flow physics that allow the prediction of engineering turbulent flows. This presentation will discuss key aspects of such simulation alongside illustrative examples. We will discuss a recently developed unstructured overset grid methodology and its application to particle-resolved DNS […]

Rapid, quantitative molecular diagnostics in the field, at home, and in resource poor settings is needed for evidence-based disease management, control, and prevention. Conventional molecular diagnostics requires extensive sample preparation, sophisticated instruments, and trained personnel, restricting their use to centralized laboratories. To overcome the limitations of laboratory-based procedures, we designed a simple, inexpensive, hand-held, smartphone-based […]

Variable geometry “morphing” structures can achieve different geometric configurations through overall deformation, but usually many actuators are required for shape control. In this talk we consider a particular type of morphing structure that is able to switch configuration with only a few actuators. It is based on the concept of embedding by design local energy […]
