Associate Professor Ilze Brigita Ziedins
BA (Waikato), PhD (Cambridge)
Ilze Ziedins joined the department in 1993.
Research | Current
Ilze's primary research interest is the modelling, analysis and optimisation of stochastic networks, with particular application to communications networks, transportation networks, and latterly, healthcare systems.
Particular themes that she is currently working on include
- Phase transitions and controls in tree loss networks
- System optimal and user optimal admission and routing controls in queueing networks
- Modelling and optimisation of patient flow in hospital systems.
