Donya Frank-Gilchrist ’06

Donya is a research oceanographer with the US Geological Survey. She recently published an article on one of the first direct measurements of vortex-trapped sand grains by turbulent coherent structures or vortices shed from ripples, which was hypothesized over 30 years ago. Understanding these small-scale processes can help us improve the accuracy of large-scale sand transport predictions. This research was conducted with the U.S. Naval Research Laboratory and the Naval Meteorology and Oceanography Command of the U.S. Navy.
