- Senior Lecturer
I came to the Department of Engineering Science in 1998 as a Lecturer, after completing my PhD in Mathematics. I was promoted to Senior Lecturer in 2006. My research interests are Network Optimization, Simulation and Statistical Modeling. I am a member of the Network Design and Simulation Group, inside the Operations Research Group at The University of Auckland.
I am currently involved in three research projects. The first project concerns the optimal design and simulation of Storage Area Networks, which is in collaboration with members of the Storage Systems Research Center at UC Santa Cruz. The second project is optimal knot placement (model selection) for fitting of regression splines, in collaboration with members of the Centre for Research into Ecological and Environmental Modeling at the University of St Andrews, Scotland. This work is primarily used for Environmental Impact Assessment of Engineering projects in Europe. The third project is optimization and statistical modelling for healthcare delivery, in collaboration with the ADHB, members of the Bioengineering Institute at The University of Auckland, and Surgeons at Starship Hospital and the Department of Orthopaedics, Auckland.
