Research | Current
My main research interests are the application of Operations Research to complex systems, in particular the formulation of optimisation and simulation models and the development of advanced techniques for solving these models. Currently I am focusing on:
- improving health delivery services;
- modelling to inform government policy;
- building intelligent (computing and storage) clouds;
- conceptual modelling for simulation;
- developing innovative optimisation software; and
- simulating construction projects.
I co-founded the Operations Research Union Analytics (ORUA) research group. ORUA’s research programmes realise innovative tools for OR and Analytics for use across all the application areas. One such tool is Dippy, an open source Python integration of the open source Python mathematical modelling language PuLP and the open source C/C++ integer programming solver DIP. Dippy has been downloaded over 300,000 times since 2010.
I am actively working with industrial partners and have either collaborated with and/or consulted for: The Ministry of Health, NZ; The Ministry of Social Development, NZ; Auckland, Waitemata, Counties Manukau, Waikato and Mid-Central District Health Boards, NZ; Steel and Tube, NZ; Hewlett Packard Labs, Palo Alto, USA; ICS Consulting, UK; M & G Investments, London, UK; Intergen, NZ; OneNet, NZ; The Ministry of Education, NZ; and Hose Manufacturers Ltd, NZ.
