PhD Candidate Nathaniel R. Bristow - "Turbulent Flow Structure Associated With Interacting, Laterally Offset Barchan Dunes"
Barchan dunes are three-dimensional, crescent-shaped bedforms which, as they migrate in the direction of the overlying wind or water flow, interact with their neighboring bedforms. Smaller, faster migrating barchans will overtake and collide with larger, slower moving ones, resulting in complex morphological changes and enhanced sediment erosion. The primary aim of this study is to elucidate the associated turbulent flow structure which is hypothesized to drive the morphodynamics of such barchan–barchan interactions.

PhD Candidate Kirsten M. Kozlovsky - "Additive Manufacturing 0f Ultra-High Molecular Weight Polyethylene Under Applied External Pressure"
Additive Manufacturing (AM) has been widely applied to many material classes and economic sectors. AM is of special interest to the medical device industry because of the need for complex geometries, the economics associated with tool elimination, and the ability to democratize production. Unfortunately, AM materials currently are lacking with respect to wear resistance.
