Biography

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.
