Closed. This professor is continuing with Fall 2025 apprentices on this project; no new apprentices needed for Spring 2026.
Marangoni effect is used by water striders (Veliidae) and rove beetles (Staphylinidae) to induce an ultrafast escape response against inter- or intra-specific predators. However, it is unclear if the surfactants secreted by these insects, that reduce surface tension of water, can also affect predator’s locomotion during the chasing.
Role: Film insects, make physical modes, biomechanical analysis, and write report.
Qualifications: Enthusiasm to work with insects. Interest in animal locomotion and fluid dynamics.
