Geoff Willmott’s Research Pages

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 a high-speed camera, which we will use to study dynamic microfluidics (among other things). There is a YouTube channel with some videos.

My work is presently supported by the Marsden Fund, the MacDiarmid Institute (one of NZ’s Centres of Research Excellence) and a Rutherford Discovery Fellowship. A large proportion of work prior to October 2013 was enabled by MBIE funding (Fast Fluidic Microanalysis NERF grant).

About Me

See my profile. I grew up just down the road from the University in Mt Eden and attended local schools. I have previously worked at the following places:

Along the way I have picked up work experience as an apprentice fitter-welder in a quarry, and at management consultancies in Auckland and London. I have various interests outside of work, especially in the sporting arena, and I am an active club rugby referee at premier level.
