About

William Stewart is a leading figure in the biomechanics and sensory ecology of predator-prey interactions, with a particular focus on the remarkable escape behaviors of larval zebrafish. His work has fundamentally reshaped our understanding of how prey fish detect and respond to threats. Stewart’s most influential contribution, published in 2014 and cited over 90 times, revealed that larval zebrafish evade predators by sensing the subtle bow wave generated by an approaching attacker, demonstrating a sophisticated hydrodynamic sensing mechanism. He further advanced the field with his 2017 study, which showed that prey fish dynamically alter their escape strategy based on the direction of the threat—choosing either a performance-optimized or a random trajectory to maximize survival. This work challenges classical escape theory and provides critical insights into the neural and mechanical basis of rapid decision-making under predation risk. Stewart’s research bridges sensory biology, fluid dynamics, and behavioral ecology, offering a compelling model for understanding how animals integrate sensory cues to execute life-saving maneuvers. His findings have profound implications for evolutionary biology and robotics, inspiring new approaches to designing autonomous evasion systems.
