I am Christina Chung, an Assistant Professor in Informatics at the Indiana University Bloomington. I study how to design systems to support health and wellness. Specifically, I conduct research on how ubiquitous computing and personal informatics data can be shared to support relationships, to motivate health behavior, and to support clinical care.
I hold a M.B.A and B.B.A in Information Management from the National Taiwan University, where I conducted research on designing embedded intrusion detection systems. In my previous life, I also worked as a software engineer in IBM Greater China Development Lab, Taipei, Taiwan to design industrial solutions that integrate novel technologies and complex enteprise systems, and in IBM Research Collaboratory Taiwan to conduct service innovation research in health and wellness.
Consumer self-monitoring smartphone apps have been widely studied and used to promote healthy behavior change. People increasingly turn to these apps and wearable devices for health management. Datasets collected through these apps may potentially enrich clinical care without adding new user burdens.
In this project, we sought to understand provider goal, needs, and their experience of use and non-use of lifelog data in chronic disease/symptoms management to support future design of personal informatic tools.

In this project, we partnered with UW Medicine, Group Health Research Institute, and Family Medicine of Yakima to understand the adoption of two blood pressure kiosks in clinic settings and how it might affect the clinic workflow.
We employed a series of mixed approches including observation in staff meetings and waiting room, focus groups, and patient surveys before the kiosks launching and are continuously observing the long-term usage of these kiosks.
Goal setting theory has been studied and adopted in a variety of domains such as game, education, and health behavior change. In this project, we sought to examine whether having two goals – a primary goal and a backup goal – rather than one might affect people’s goal-setting behavior, which suggested but not further studied in previous literature. We designed three studies - a lab experiment, an online experiment, and a field experiment - to understand how different goal-setting scenarios predict performance.

Temperature information is seen as intimate and reflective of health and comfort, and so sharing it between people in remote relationships may be particularly valuable for supporting those relationships.
In this project, we probed how people in remote relationship might react to the information and what their concerns might be. We are also planning on future home deployment study to understand how people would actually use such information and to validate our preliminary findings.
We conducted contextual inquiries in a Multiple Sclerosis (MS) clinic with over 300 MS patients. MS is a chronic, progressive disease and case manageers (CM) played a critical role to manage the complex symptoms. Results from interviews and observations indicated inadequate information resources and systems led to higher effort and stress to manage individual's cases and orders. Based on the results, we developed a conceptual workflow model to serve as an information source architecture and a reference model of user interface design.
