The major determinant of walking's metabolic cost is the work required to redirect the centre of mass velocity during step-to-step transitions. My first aim was to isolate transitions from other contributors to walking mechanics. The results demonstrated that sagittal plane rocking reproduced the important characteristics of walking's transitions including a strong dependence of work on step length and a proportional increase in metabolic cost. My second aim was to use rocking to gain insight into pathological gait's elevated cost. Physics-based mathematical models predict sub-optimal transitions occur when one or both legs are unable to generate mechanical power with the optimal timing and magnitude, requiring a greater magnitude of total work and an increase in metabolic cost. I tested this prediction by immobilising the ankle joints of healthy subjects to simulate sub-optimal transitions and found that joint immobilization indeed caused sub-optimal transitions thereby increasing transition work and metabolic cost.

Understanding Mammalian Locomotion will formally introduce the emerging perspective of collision dynamics in mammalian terrestrial locomotion and explain how it influences the interpretation of form and functional capabilities. The objective is to bring the reader interested in the function and mechanics of mammalian terrestrial locomotion to a sophisticated conceptual understanding of the relevant mechanics and the current debate ongoing in the field.

In the fight against zombies, our most important weapons are our brains. It's time to unleash them. Think you know a thing or two about zombies? Think again. If you’re going to keep your wits – and your brains – about you during a zombie attack, you need expert advice. Braaaiiinnnsss!: From Academics to Zombies gathers together an irreverent group of scholars and writers to take a serious look at how zombies threaten almost every aspect of our lives. Spawned from the viral publication "When Zombies Attack!: Mathematical Modelling of an Outbreak of Zombie Infection," this multidisciplinary book draws on a variety of fields including biology, history, law, gender studies, archaeology, library science and landscape architecture. Part homage to zombie films and fiction, part cultural study, this collection humorously explores our deep-seated fear of the undead. Engaging and accessible, Braaaiiinnnnssss! will amuse academics and zombie fans alike. Publié en anglais.
