Research

Gar Goei's research focuses around decision-making under uncertainty, and developing models, frameworks, methods and algorithms that help decision-makers go from data to decisions. In his primary stream of research, he has applied techniques in robust optimization to the solution of optimization problems in queueing networks. More recently, he is studying what divides existing paradigms in machine learning and optimization and is developing and proposing new ways to integrate them harmoniously. His research is primarily applied to business areas such as service operations management, supply chain managment, healthcare operations management, and energy and water. His research has been published in journals such as Operations Research and Manufacturing & Service Operations Management.
