Since completing my PhD in mathematical modelling I have worked on various projects and I have modelled a variety of processes including the flow of food through the intestines, granular mixing and discharge from a silo, predicting shelf life of milk powders, rheology of milk products, open channel flow of Newtonian and non-Newtonian fluids as well as a number of others. I spent a year as a postdoctoral researcher at the Riddet Institute before taking up a 2.5 year position lecturing in the mathematics department. I was then awarded a Royal Society of New Zealand Postdoctoral Fellowship for a period of two years where I worked to modelling the flow of granular materials through silos. In 2017 I was awarded a Marsden Fast Start for a period of three years to further investigate granular mixing in silos where there is more than one type of granular material. I am also working with the researchers in the School of Agriculture and Environment to model volcanic flow processes.
My main area of research is understanding the physics of dense granular flow through physical experiments and mathematical modelling. I want to be able to describe and accurately predict mixing and dynamics of granular materials in industrial processing conditions. This is important for many industries including the pharmaceutical and food processing sector because accurate understanding of granular flow dynamics can lead to cost savings and improved quality control.
I am currently funded by a Marsden Fast Start (MAU1712) for the project “Understanding friction in granular mixtures: an experimental and modelling study”. I am also interested in more general Newtonian and non-Newtonian fluid flows including volcanic eruption modelling, open channel flow, and flows of fluids with yield stresses such as thick muds.
