Jay (JungKyoon) Yoon is an associate professor in the Department of Human Centered Design at Cornell University, where he leads the Meta Design & Technology Lab. Yoon's research investigates how products can be systematically designed to enrich users' momentary as well as long-term experiences. He builds on knowledge and methods from human-centered design, human-computer interaction, and positive psychology.

Yoon's research findings and design supports (i.e., design methods and tools) have been applied to and iteratively improved through several industry projects. These projects covered multiple design contexts and business domains, including a smart home service, an airport crew-center, a museum tour, and a brand loyalty program.

Yoon has an educational background in industrial design and computer science (BA and BE from Handong University, South Korea). He earned his MSc. degree from the program "Design for Interaction" at the Faculty of Industrial Design Engineering of Delft University of Technology, the Netherlands. At the same university, he received his Ph.D. degree with a focus on emotion-driven design. He previously worked as an interaction designer at Naver Corporation, where he supported the development of an Internet search service, social media, and product simulations. Prior to joining Cornell, he taught in the Industrial Design division at the University of Liverpool, United Kingdom, as an assistant professor.
