Although organisms obey the same physical laws as inanimate objects the evolutionary implications of these laws are often neglected. Physical factors influence the fitness value of traits and play an important role in the course of evolution. Our research ignores disciplinary boundaries and is linked by the central theme of using physics and engineering principles as a way of understanding complex problems in biology. Our work is characterized by strong interdisciplinary, collaborative links across academic areas in the University, and by novel approaches to addressing questions at the interface between biology and physics.
Running and Jumping
Jumping insects provide spectacular examples of precisely manipulated speed, spin, energy and power. In the blink of an eye, jumping insects catapult themselves toward targets and away from predators. We study the mechanics of how various insects control the muscles, joints, and even springs, that they use to fling themselves through the air. Our research is ballistic physics applied to living beings at high velocities.
How animals hear, see, smell and taste the world around them is a key determinant of their behaviour, and underpins how they respond to environmental change. We investigate the structure and function of animal sensory systems, by integrating experimental studies in the lab and field with computational models, and study how variation in sensory perception impacts on social and reproductive behaviour, ecological interactions, and evolution.
Biological Fluid Dynamics
Work in this area focuses around biological fluid dynamics at a number of scales, from the whole organism down to the level of cellular motility. We have been particularly successful at introducing physical thinking into our understanding of the evolution and function of sperm length and have provided key insights into the individual-level effects of environmental viscosity. We use theory, experiment and field studies to address a number of questions from how sperm swim, why bacteria have different shapes, and how bacteria respond to viscosity in their environment.
