Advances in generative AI and conversational systems are rapidly changing how health and medical information is delivered.

We study how digital technologies, including AI and chatbots, can support interactive health communication tailored to individuals’ questions and concerns rather than relying solely on one-way information delivery.

In the fields of vaccination and preventive health, we aim to develop communication environments in which people can easily access the information they need and feel comfortable expressing questions and concerns.

We also examine not only the effectiveness of AI-based health information, but also its trustworthiness, how users interpret it, and how it may influence decision-making, with the goal of exploring future models of health communication in a society where humans and AI increasingly coexist.
