Andreas has worked in real-world applications of optimisation for over 25 years, including in supply chains, logistics, mining, services (rostering) and energy.  Recent work includes rail planning and scheduling for Pacific National through a Linkage grant and methods using machine learning to improve the performance of optimisation algorithms as part of a ARC Discovery Project with RMIT. Andreas is a Senior Fellow with the Australia Indonesia Centre leading the research on Transport and Logistics in the PAIR program. His research is focused on methods for solving large-scale integer programming problems, including decomposition methods and matheuristics that combine mathematical programming approaches with metaheuristic search.
