We are the Systems Optimization & Decision Analytics Lab (SODALab) based in the Department of Computing Science at the University of Alberta and the Alberta Machine Intelligence Institute (Amii) in Edmonton, Canada. Our research seeks to address uncertainty and strategic behaviors in systems modeling, optimization, learning, and decision-making, using tools and insights from computer science, economics, and operations research.
At SODALab, we view much of the modern world as systems of interacting, often self-interested, strategic agents who share and compete for limited resources amid varying dynamics and uncertainty. This perspective is particularly relevant to safety-critical systems and networks that significantly impact environmental, social, and economic sustainability, such as electrical grids, transportation, and data centers. In these systems, complex interactions among multiple stakeholders are common, and ensuring robustness and resilience against unforeseen disruptions is essential. Moreover, public acceptance of unexplainable results in these contexts is generally low, if not intolerable. This drives our primary research focus: developing mathematical and algorithmic tools with formal performance guarantees for decision-making under uncertainty and strategic behaviors.
