Ruebeck’s interests include industrial organization, evolutionary game theory, econometrics, and agent-based modeling. His research has been supported by grants from national and local groups. A grant from the National Science Foundation (NSF) with colleagues in computer science and engineering supports his work on interdisciplinary, environmental research that uses computational simulation to incorporate market incentives in environmental policy-making. He teaches classes that are part of another NSF grant supporting computational methods in the curriculum and a Mellon Grant for interdisciplinary teaching. He also has received an inter-institutional grant to study the local food supply chain.
