My research is mainly oriented towards the application of mathematical optimization methods. I have worked in the energy domain at IfA in Zurich, and in my current position at ACFR, Sydney, I am also investigating models for mining applications. These domains invariably require the co-optimization of continuous quantities (such as voltages, currents, concentrations, grades, etc) and binary variables (on-off decisions, logic constraints). This requirement generally results in hard computational problems.

Applications of Optimization
I develop new mathematical models that enable the optimal operation of systems, in particular large engineered systems such as power networks and mining production networks.
Decomposition of Large Scale (MIP) Optimization Models
I do research on practical methods for solving large, structured optimization problems. These arise, for example, when dealing with the operation of large engineered systems. They also appear in the context of solving scenario based stochastic models (e.g., in multi stage stochastic optimization).
Robust Scheduling and Optimization
I am also interested in optimization models entailing uncertainties, and in particular in methods to address these uncertainties in a robust fashion. The primary application domains of my research in this area have been in the control of power electronic systems, and optimization of industrial production processes.
