Biography

I am a New Zealander who studied at the University of Cambridge (UK), obtaining a PhD in shock physics in 2005. I returned to New Zealand the following year to a postdoctoral position with the Nano and Micro Fluidics team at Industrial Research Limited (now Callaghan Innovation) in Lower Hutt. I developed an interest in nanofluidics, and was appointed as a Principal Investigator with the MacDiarmid Institute in 2010.

I was awarded a Rutherford Discovery Fellowship in 2012, and started as a Senior Lecturer in the Department of Physics at the University of Auckland in October 2013.

 

Research | Current

Nano- and microfluidics is a field with rich potential for applications in medicine, sensing, biotechnology and industry. My research involves the application of physics to fundamental and practical problems, through both theory and experiments. I have a general interest in nanofluidic transport – the motion of liquids (and particles within them) on very small scales. More specifically, I have worked extensively on tunable resistive pulse sensing, a nanofluidic technology commercialized by Christchurch-based Izon Science. I have studied non-wetting systems involving interfacial slip, superhydrophobicity and capillary tubes. I hope to develop projects using new nanofluidic tools to study ‘soft’ nanomechanics. We have recently obtained a high-speed camera, which we will use to image the dynamic behaviour of microfluidic droplets.
