Associate Professor Geoff Willmott is a New Zealander who studied at the University of Cambridge (UK), obtaining a PhD in shock physics in 2005. The following year, he returned to New Zealand and joined the Nano and Micro Fluidics team at Industrial Research Limited (now Callaghan Innovation) in Lower Hutt. He developed interests in nanofluidics and dynamic microfluidics, and in 2012 was awarded a Rutherford Discovery Fellowship and a Marsden Faststart to work in these areas. In 2013 he moved to the Department of Physics and Chemistry at the University of Auckland. He has been a Principal Investigator with the MacDiarmid Institute for Advanced Materials and Nanotechnology since 2010, and is the Institute’s Deputy Director for Commercialisation and Industry Engagement.


Sina Safaei


MSc, Nanotechnology, Sharif University of Technology, Iran

Sina’s PhD research focuses on theoretical and computational studies to understand the way that soft matter interacts, and self-assembles into coherent phases and higher-order structures. Sina performs large-scale molecular dynamics simulations to study the dynamics of (for example) Janus particles in fluid flows.

Santhosh Kumar Pandian


MSc, Materials Science, Tampere University of Technology, Finland

Santhosh is studying drop impacts of non-Newtonian fluids on structured surfaces in the Dynamic Microfluidics Laboratory. This work involves high-speed photography of the impact events, and analysis of the physical processes observed in the resulting movies. Although Newtonian fluids and impacts on flat surfaces are well studied, everyday applications often involve more complex fluids and rough surfaces.

Qaisar Latif


MEng, Materials Science and Engineering, University of Kiel, Germany

Qaisar’s PhD project focuses on experimental studies to understand novel emergent properties of soft matter. He is employing various microfluidic techniques to study individual and collective particle dynamics in a colloidal system. One aim of the research is to further elucidate the role of slip in particle dynamics.

Nicola Lacalendola


BEng (Hons), Electronics Engineering, Newcastle University, UK

Nick’s main area of research towards a PhD is the mechanics of soft materials on the micron and nanoscale. He is currently working on translating a novel ion-based technique which characterizes micromechanical properties to the nanoscale. This is a comparative study where experimental results are benchmarked against well-known techniques (e.g. atomic force microscopy) while the analysis and the development of a bespoke analytical model are accompanied by finite element simulations.


Dr Ayoub Abdollahi


PhD, Mechanical Engineering, The University of Auckland

Ayoub has joined the Dynamic Microfluidics Lab as a Research Fellow in 2020. He completed his PhD and was a Teaching Fellow in the Department of Mechanical Engineering at UOA. His research interests are in the fields of experimental and computational heat transfer, computational fluid dynamics (CFD), two-phase flow, and microfluidics. He is working on an experimental project focusing on the interactions between drops and surfaces in a heated environment.

Dr Steve Wells


PhD, University of Wollongong, Australia.

Steve is a Postdoctoral Fellow working on high-speed photography of fluids, and superconductivity. He is interested in fluid interactions with surfaces (e.g. drop impact) for various fluids and surfaces – including ferrofluids and superhydrophobic surfaces. He is also working on a project to make and investigte liquid superconductors.


Dr Ankita Gangotra


PhD, The University of Auckland (2019)

MEng, Electronics with Nanotechnology, University of York, UK

Ankita moved to New Zealand in late 2015 for a PhD project on aspiration of soft particles using nanoscale pipettes, funded by the MacDiarmid Institute. Following graduation, she has worked with a local start-up and as an intern with the Office of the Prime Minister’s Chief Science Advisor.

Dr Matheu Broom


PhD, The University of Auckland (2019)

MPhys (Hons), The University of Hull, UK

Matheu’s research focussed on the role of surface patterning on water repellant surfaces – including drop impact on micropatterns. He developed a range of experimental methods using soft lithography, high-speed photography, and digital image analysis during his PhD. He is now working at Engender, a local start-up.

Dr Miguel Balzan


PhD, Mechanical Engineering, University of Alberta, Canada

Miguel was a Postdoctoral Fellow with the group from 2018-20 with expertise in fluid mechanics and especially spray engineering. He worked in the Dynamic Microfluidics Laboratory on our MBIE-funded project relating to spray drying of dairy products. Miguel obtained a permanent role in the USA in 2020.
