Optimisation of droplet roll-off on patterned surfaces


Investigation through molecular dynamics simulations the surface features that optimise the detachment and roll-off of liquid droplets.

Program type



The detachment of water droplets from structured surfaces is important in many technological applications, such as the collection of atmospheric water. The dynamics of water detachment can be investigated in silico, where different chemical and geometrical patterns can be designed to optimise both water condensation onto and detachment from a surface. We will develop new approaches for the fabrication of nanostructured surfaces, and we will investigate their potential applications. In this project we will expand on our recent discovery of micropatterned surface coatings for water capture. For a video illustrating the principle visit

Additional information

The project primarily involves performing computational experiments using a molecular dynamics, in collaboration with Dr Asaph Widmer-Cooper in the School of Chemistry and Prof Shaun Hendy at the University of Auckland. Matching experiments using advanced surface structuring techniques will be performed both in collaboration with other members of the lab and through external collaborations. Interested students should source their own scholarship, as detailed on the University’s website. 

HDR Inherent Requirements

In addition to the academic requirements set out in the Science Postgraduate Handbook, you may be required to satisfy a number of inherent requirements to complete this degree. Example of inherent requirement may include:

- Confidential disclosure of a pre-existing or current medical condition that may hinder your performance in your degree (e.g. heart disease, pace-maker, significant immune suppression, diabetes, vertigo, etc.);
- Ability to perform independently and/or with minimal supervision;
- Ability to undertake certain physical tasks (e.g. heavy lifting);
- Ability to undertake observatory, sensory and communication tasks;
- Ability to spend time at remote sites (e.g. One Tree Island, Narrabri and Camden);
- Ability to work in confined spaces or at heights;
- Ability to operate heavy machinery (e.g. farming equipment);
- Hold or acquire an Australian driver’s licence;
- Hold a current scuba diving license;
