Dr Irina Boiarkina


Irina has recently been appointed as a lecturer at the Department of Chemical and Materials Engineering, after working as a postdoctoral fellow for the Industrial Information and Control Centre (I2C2) since 2013. Before starting her PhD in photocatalytic wastewater treatment, she worked as a graduate process engineer at Harrison Grierson Consultants in water treatment plant design. Her research has been focused on milk powder quality, working with Fonterra on their industrial spray dryers. It looks at being able to predict quality metrics in real-time, and has been based on both experimental and mathematical modelling work. The research into milk powder has inspired her to investigate powders in more depth, specifically looking at the relationship between individual particle properties and bulk powder behaviour. 

Research | Current

Irina's current research is focused on understanding the link between microscopic particle properties and bulk powder beaviour.

  • Understanding bulk powder properties such as bulk density, flowability, mixture homogeniety, dissolution behaviour and compactability.
  • Linking these bulk properties with microscopic particle properties such as particle size and morphology characteristics, interparticle forces, chemistry, surface roughness and surface area.
  • Understanding interactions between different microscopic properites.
  • Understanding dissolution and extraction kinetics of powders.
