About

Liat Levita is a leading researcher in the intersection of human-robot interaction and psychophysiology, with a primary focus on stress reduction and emotional well-being. Her most cited work, "Interaction with the Paro robot may reduce psychophysiological stress responses" (2016, accumulating over 50 citations), represents a landmark contribution to the field of social robotics. In this research, Levita demonstrated that interaction with the Paro therapeutic robot—a seal-like robotic companion—can significantly lower psychophysiological markers of stress, including cortisol levels and heart rate variability. Her findings have profound implications for healthcare settings, particularly in geriatric care, mental health treatment, and hospital environments where stress management is critical. By rigorously measuring both subjective mood improvements and objective physiological responses, Levita provided compelling evidence that robotic companions can serve as effective, non-pharmacological interventions for stress reduction. Her work bridges robotics, psychology, and neuroscience, establishing a foundation for future studies on how embodied AI can enhance human well-being. Levita’s research continues to influence the design of therapeutic robots and their integration into clinical practice, making her a pivotal figure in the growing field of socially assistive robotics.
