About

Dr. Alethea Nagahara is a pioneering researcher at the intersection of gerontechnology and artificial intelligence, dedicated to transforming elder care through socially assistive robotics. Her most-cited work, "Promoting Cognitive Health in Elder Care with Large Language Model-Powered Socially Assistive Robots" (2025, 13 citations), represents a landmark contribution to the field. In this study, she demonstrates how large language models can be integrated into in-residence robotic systems to monitor, assess, and promote cognitive health in aging populations—offering a scalable solution to the global challenge of age-related cognitive decline. By enabling early detection of cognitive changes through natural, everyday interactions, Nagahara’s work bridges the gap between cutting-edge AI and compassionate care. Her research not only advances the technical capabilities of socially assistive robots but also addresses critical ethical and practical considerations for deploying such technologies in sensitive care environments. As a thought leader in human-robot interaction and cognitive health, Nagahara continues to shape how we design intelligent systems that support dignity, independence, and well-being for older adults.
