4D structural characterization of carbon-sequestering cements
This project will use high resolution 3D X-ray computed tomography to characterise the evolving structure of reactive magnesium cement materials over days- to months-long time frames, in order to learn how to optimise cement composition and initial structure to enhance CO2 uptake and cement strength.

Impact of surface roughness on fluid equilibribrium
Fluid flow in porous media combines the impacts of many complex phenomena: fluid properties, solid structure, and the infacial interactions between fluids and solid phases. This project aims to uncover the reasons behind some fundamental differences between experiments conducted in glass bead packs and those conducted in geologic systems (rocks).
Environmental Physics
Nanobubbles
Nanobubbles are simply nanosized bubbles. What makes them interesting? Theory tells us they should dissolve in less than a second but they are in some cases stable for days.
Surface forces and the behaviour of colloidal systems
We measure the basic forces that operate between molecules that are manifest at interfaces. These forces control the stability of colloidal systems from blood to toothpaste. We use very sensitive techniques that are able to measure tiny forces with sub nanometer distance resolution. Understanding these forces enables us to predict how a huge variety of colloidal systems will behave.
Materials Science and Engineering


Mathematical making
Explore the geometry and symmetries of surfaces and other mathematical objects and explore their relevance in physical, chemical and biological contexts.
Exploring novel X-ray scanning trajectories
The first 3D X-ray microscopes used viewing angles evenly spaced in a full 360 degrees around the sample. Recent innovations have freed us from this constraint: the microscopes at the ANU CTLab can utilise ever stranger and more innovative scanning patterns. However, this new freedom is not well explored.
X-ray speckle tracking
In this project the student will explore a cutting-edge "speckle tracking" method for measuring X-ray phase, in which computational image analysis is used to infer the X-ray phase from deformations in a known speckle pattern. This has both theoretical and experimental components.


Soft Condensed Matter: Molecules made by Threading
Of great recent interest is the subject of rotaxanes. Rotaxanes are molecules where one or more ring
components is threaded onto an axle that is capped on both ends with stoppers to prevent the rings from
falling off. These systems exhibit complex and fascinating physics.

Machine learning for tomographic reconstruction.
Machine learning (and in particular deep-learning) methods have been at the centre of amazing progress in the field of computational image analysis. In this project the student will work to develop machine-learning algorithms for tomographic reconstruction, and deploy these algorithms at the ANU CTLab imaging facility.

X-ray scatter in 3D microscopes
X-ray scatter is most significant when imaging very dense/large samples: e.g. metal parts, large 3D printed components, or samples imaged on the CTLab's new "whole core" scanner. The student will develop methods to correct for its effects, both in-hardware (i.e. at the microscope) and in-software (i.e. image analysis).
Deblur by defocus in a 3D X-ray microscope.
This project will involve building a unified model of several theoretically-complex X-ray behaviours within the microscopes at the ANU CTLab, drawing from statistical and wave optics: spatial partial-coherence, refraction, and spectral interactions. The student will then apply this model to improve imaging capabilities at the ANU CTLab.


Three-dimensional crystalline structures from two-dimensional hyperbolic tilings
A variety of projects are available that will contribute to the enumeration and characterisation of 3-periodic network structures via the tiling of periodic minimal surfaces and thereby enhance our understanding of self-assembled structures in nature.
Colloidal systems in highly concentrated salt solutions
We are studying colloidal systems in highly concentrated salt solutions. Here a number of surprising and unexplained things happen that are associated with surprisingly long-ranged electrostatic forces
Neutron and X-ray imaging/tomography techniques at ANSTO and AS (Australian Synchrotron)
This project involves working with scientists from imaging beamlines at the Australian Synchrotron (IMBL, XFM, MCT) and the Lucas Heights nuclear reactor (DINGO) to develop multi-modal, multi-scale, and dynamic imaging and tomography techniques alongside computational imaging scientists from ANU.

Ghost imaging in the third dimension
In ghost imaging, images are formed based on photons that have never interacted with the sample. 3D ghost imaging was first performed in 2018 by scientists at ANU and international collaborators at the European Synchrotron Radiation Facility: the student will work with these scientists to further advance the field.
