About

Dimitra Tsovaltzi is a leading researcher at the intersection of human-computer interaction, socially interactive agents, and affective computing. Her work focuses on designing intelligent systems—from serious games to industrial robots—that can perceive, interpret, and respond to human emotional and social signals. A major contribution is her development of the PAD (Pleasure, Arousal, Dominance) model of flow for emotional co-regulation in human-robot collaboration, enabling cobots to support workers' optimal experience through adaptive, theory-based interventions. Her research on mapping social signals from facial expressions to robot-avatar behavior provides a foundational framework for creating more natural and effective human-robot interactions. Tsovaltzi's work has been published in key venues including the influential *Handbook on Socially Interactive Agents*, and her papers on serious games with socially interactive agents and emotional co-regulation in industrial settings are shaping the next generation of collaborative robots. With a growing citation impact, her research is essential reading for anyone interested in building socially aware AI systems that can truly work alongside humans.
