My current primary research work involves optimizing workload allocation across a single / multiple data centres such that total energy cost is minimised, as part of the EU FP7-Transport funded project GENiC.
Previously I have worked on fleet maintenance optimization for trains, as part of the EU FP7-Transport funded project MAXBE. The problem required scheduling planned periodic maintenance, while incorporating uncertainty regarding possible unplanned maintenance requirements due to operational failures, such that a time-variable fleet demand profile is met, and exam due dates are respected, where possible.
Prior to the work on condition-based maintenance optimization, I worked on optimization for energy management systems, in particular automation of energy consumption in the residential sector. This work was cofunded by the Irish Research Council and Intel Labs Europe.
My PhD was primarily focussed on using conflict-directed search to identify critical variables for constraint programming (in particular applied to machine scheduling problems), amongst other topics.
