About
Sachini Rajapakse is a rising researcher at the intersection of human-robot interaction and gerontechnology, whose work investigates how older adults perceive and engage with social robots. Her research centers on designing multi-robot systems that can meaningfully support aging populations, with a particular focus on how robot intelligence levels and social behaviors shape user trust and acceptance. In her most cited work, “Older Adults’ Perceptions of Robots with Differing Intelligence in Social Multi-Robot Interactions” (2025), Rajapakse directly manipulated robot intelligence in multi-robot scenarios—a novel approach that moves beyond single-robot studies to reflect real-world assistive environments. While her career is still in its early stages, this foundational paper has already garnered attention for its methodological rigor and practical relevance to the growing field of socially assistive robotics. Her contributions are especially timely as societies worldwide seek scalable, empathetic technological solutions for elder care. Rajapakse’s work promises to inform the next generation of robots that are not only functionally capable but also socially attuned to the needs of aging users.
