Summary

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 moved to Macquarie University in Sydney Austrlilia and recieved a prestigious DECRA fellowship from the Australian Government. During this fellowship I was offered a Lectureship position at the University of Hull. I gladly accepted and returned back to the UK.

I have Lectured a range of courses at different universities. These include 3rd year Partial Differential Equations, 2nd year Group and Ring Theory, 1st year Introduction to Probability and Statistics, and 1st year calculus. I have also been involved in the development of a new curriculum and degree.

Research interests

Dynamics of microsystems

Colloids, bacteria and micromachines all display complex dynamical behaviour. This is due to the dynamics of an object at this scale critically depends on its physical interactions and shape. In my work I develop models to understand and model these emergent phenomena.

Postgraduate supervision

I am always happy to hear from keen prospective PhD students.

I am particularly interested to hear from students with interested in slow viscous flows, micro-machines, and collective dynamics.
