Fengyi Sun

Fengyi Sun is a first-year PhD Candidate in Health Policy and Health Economics. She is currently studying the adoption, acceptance and implementation of AI in social care for older people using mixed methods. She is particularly interested in how AI affects care provision, how older people and their families respond to its use, and what shapes its implementation in practice.

Fengyi holds an MA in Health Economics from Wuhan University and a BA in Economics from Lanzhou University. Her previous research has examined community-based care, the valuation of informal care, and health behaviours among older adults. She has also contributed to research and fieldwork on long-term care insurance in China.
