Wonchan Choi, Ph.D.
Interests & Expertise:
Dr. Choi’s general research areas are human-computer interaction, human information behavior, health information technology, with a particular focus on mobile health applications (mHealth apps) design, and health informatics. His research focuses on the user’s effective use of information systems and technology on web and mobile platforms to fulfill needs in different contexts. Recent research has focused on older adults’ health information needs and related behaviors in seeking and using health information both on- and offline and developing assistive technologies, such as mHealth apps, to support older adults’ self-management of chronic health conditions. Dr. Choi has expertise in user studies, determining the requirements of the information systems under development, learning the preferred types of user interface design, testing the usability of the systems, and examining the effects of system design on users’ perceptions of, and experiences with, the systems. Dr. Choi’s research aims to provide research evidence for developing an effective information system, services, and training modules that are aligned with the behaviors and expectations of target audiences.
Dr. Choi’s current projects investigate older adults’ credibility assessment of online health information as an important part of their health information seeking and use in the everyday life context and develop an mHealth app for older adults with multiple chronic conditions.
