Research summary
AI-generated

This researcher works broadly in decision sciences, with published work spanning multi-criteria and group decision-making methods, fuzzy/rough set theory, and behavioral economics concepts like happiness and habituation. Recent publications also branch into machine learning topics such as fairness, multimodal engagement detection, robotics digital twins, and natural language generation, suggesting a wide and varied set of collaborations. Prospective students should note the range of topics covered, as the work does not appear to center on a single narrow specialty.
