Head of Discipline (Mathematics and Statistics)

About me

I am a teaching and research academic with over 25 years experience.  I have had the privilege of teaching hundreds of students at all levels of University from first year to higher degrees in mathematics, engineering and oceanography and presenting problems in a range of disciplines that benefit from mathematical modelling.

My research interests are broad, covering all areas that can be modelled – which is surely everything!  However, in particular I like to work in fluid mechanics and industrial/environmental modelling.  I have published work on reservoir flow dynamics, flow of plastics, galvanizing of steel, design of ultrasonic nebulizers and flow in porous media among many other applications.

Teaching area

I am involved in teaching a number of units at undergraduate level, including

MAS164 – Fundamentals of Mathematics
MAS182 – Applied Mathematics
MAS161 – Calculus and matrix algebra
MAS220 – Mathematical Methods
MAS221 – Mathematical Modelling
MAS351 – Environmental and Biological Modelling

and similar units through Open Universities Australia.
I have also frequently delivered Honours units in fluid dynamics, industrial modelling, complex variables and asymptotic techniques.

Research areas

My research interests are spread across anything that can be modelled, which is surely everything.  In particular, I work in the areas of fluid dynamics and industrial mathematics, including work on reservoir withdrawal dynamics, modelling of air-jet stripping during galvanising of steel, flow over obstructions, coating of solar panels, glacial flows, non-Newtonian fluids, rock fractures and explosions in mining applications.

I regularly attend Mathematics-in-Industry Study groups, in which industry representatives propose problems that are discussed and modelled by the ensemble. I have attended such Workships in Australia, New Zealand, Ireland and South Africa – around 25 in total. These dynamic groups are highly interactive and grounded in getting to the heart of the industry problems.

Events and speaking engagements

Plenary Speaker – ANZIAM2013 (Newcastle, Australia) Feb. 3-7 2013 – “Theory and Practice of withdrawal from stratified reservoirs”

Plenary Speaker – New Zealand Mathematics Colloquium, December, 2013

Professional and community service

I am currently the co-Editor-in-Chief of the ANZIAM* Journal.  I am also a member of the executives of ANZIAM and the Australian Mathematical Society and the Chair of the Western Australian Branch of ANZIAM.

I have been a moderator at a number of Mathematics-in-Industry Study Groups (in which we collaborate with industry to solve real problems) and have attended meetings of this type in Ireland, South Africa and Australia.

For the last 15 years I have been a reader and assessor for the ARC and also an Associate editor of the Journal of Engineering Mathematics and a referee for a number of International journals in applied mathematics, engineering, oceanography, environmental science and nanotechnology.

*ANZIAM stands for Australian and NZ Industrial and Applied Mathematics and is a division of the Australian Mathematical Society.

 

Doctoral and masters supervisions

Rachel Holmes (PhD) – flow of a fluid with a free surface over bottom topography (COMPLETED 2016)

The flow of water over obstuctions generates downstream waves. However, certain bottom shapes can work to cancel waves, thus removing a significant component of drag on the underwater structures. This project aims to compute flows and shapes which have this useful wave cancelling property.

Hanan Omar (PhD) – Intrusion flow into a reservoir (COMPLETED, 2016)

Water entering a reservoir that is stratified in density will plunge downward to the level of neutral buoyancy before intruding. Since intrusions can carry pollutants or salt, it is desirable to understand these flows to assist in management of the reservoir water release strategy to optimise water quality.

Suha Al-Ali (PhD) – The withdrawal from a stratified fluid in a porous medium

Fresh water in tropical islands tends to sit in a lens beneath the ground and is a major source of fresh water.  Extracting the water without drawing in salty ocean water is an interesting problem in porous media flow.  Models of withdrawal for a range of island conditions will form the bulk of this work.

Shaymaa Shraida (PhD) – Saline Plumes in Desalination outfalls

Water left over from Desalination processes is often highly saline.  Much of this water is returned to the ocean via long pipes.  Due to its high salt content the water is very dense and sinks to the bottom where it can do significant damage to seagrasses and ocean life.  In this study we will model the plume that is generated by this saline water with a view to optimizing the process and minimizing the damage.

Wafaa Mansoor (PhD) – Blood flow in the Retina

The retina is the part of the eye that captures images that are relayed to the visual cortex.  The blood flow to this vital organ is essential in providing the required chemicals to conduct the necessary process.  Lack of blood flow due to diseases such as diabetes can lead, in extreme cases, to blindness.  In this thesis we will consider models of blood flow to the retina to compare with experimental data.
