About

Dr. Halley Wallace is a leading figure in the emerging field of ethno-fluid dynamics, with a primary research focus on the physics of human-water interaction and the biomechanics of traditional diving practices. Her major contribution lies in the systematic study of *Manu* jumping, a culturally significant water diving style among the Māori people of New Zealand. Through her highly cited 2024 and 2025 papers, "Mastering the Manu—how humans create large splashes," Wallace has pioneered the quantitative analysis of how divers perform aerial maneuvers—such as the "utkatasana" pose—and execute precise underwater V-shaped entries to maximize splash size. This work bridges cultural anthropology, sports science, and fluid mechanics, providing the first rigorous framework for understanding how the human body can be deliberately shaped to manipulate water displacement for aesthetic and competitive effect. Her research has garnered 4 citations, establishing her as the definitive authority on the subject. Notably, her work has been recognized for its interdisciplinary approach, offering a unique lens through which to study both traditional knowledge and modern physics.
