Personal profile

Biography

 I started my academic career in physics working on the dynamics of vortices in Bose-Einstein Condensates. After completing a Masters at the University of Melbourne, I moved to the University of Cambridge for a PhD in 2012. This PhD focused on the behaviour of microscopic swimming objects in water, with a particular focus on swimmers that use filamentous or ribbon like appendages. I then took up a postdoctoral position at Cambridge, in which I started working with experimental groups on the dynamics and design of microscopic devices. In 2018 I then moved to Macquarie University to take up a Lectureship position.

Research interests

My research explores the dynamics of microscopic objects in fluids. This research improves our understanding of bacterial swimming, colloids, active matter and the dynamics of micro-machines. At these small scales motion critically depends on an objects shape and the interactions with its neighbours. I employ analytical approximations and simple numerical techniques to explore the effect of geometry on dynamics and to develop simple models for recent experimental systems. These investigations can occur on both a fundamental level and in close collaboration with experimental groups around the world.
