Sarah-Jeanne Royer

Sarah-Jeanne Royer is a Senior Professor at Hawaiʻi Pacific University specializing in marine pollution, environmental science, and coastal engineering. Her research focuses on plastic pollution dynamics, including microplastic formation through brittleness on beaches, buried plastic underestimation in Hawaiian coastal zones, and concentration gradients across the Southwest Indian Ocean. She has published extensively in 2025, including studies on North Pacific Garbage Patch cleanup impacts and rise velocity of polyolefin plastics under natural Hawaiian conditions. Her work integrates coastal management and conservation, advancing harmonized assessment methodologies for global plastic pollution mitigation.
