I am a Ph.D. student in the University of Michigan School of Information, advised by Dr. Mark S. Ackerman. I am a member of the SocialWorlds research group and the Michigan Interactive and Social Computing (MISC) group. My major research interests include Human-Computer Interaction, Computer-Supported Cooperative Work, Ubiquitous Computing and End-User Programming. More specifically, I am interested in the intersection of communities and Ubiquitous Computing where people with diverse background live their lives within a smart environment full of intelligent everyday objects. Currently, I am investigating how we could design sensor-based mobile platforms to support informal health care at home for people with severe injuries. I received BS and MS in Computer Science and Information Engineering from National Taiwan University, Taiwan, and a MS in Information from the University of Michigan.


I have assisted in teaching graduate and undergraduate courses as a graduate student instructor (GSI) at the School of Information for SI 502: Networked Computing: Storage, Communication, and Processing, with Professor Charles (Chuck) Severance, and SI 110: Introduction to Information Studies, with Professor Jeff Mackie-Mason.

Supporting Informal Healthcare Teams at Home

Being seriously injured with physical disabilities, such as spinal cord injuries, imposes sudden and significant changes on people's lives. Making the transition from the hospital to home is a daunting process as various aspects of people's lives have to be conducted in drastically different ways due to the severe injuries, not to mention losing the constant support and guidances from trained health professionals at the hospital. Moreover, due to the loss of physical abilities and senses, there are extra procedures (e.g., monitoring hydration and doing pressure relief) needed to be incorporated into individuals' lives to maintain a healthy status.

Based on the findings from interviews and focus group, we argue that Internet of Things (IoT) offer great potentials to support the care team (e.g., individuals, personal assistants, caregivers, and clinicians) in this transition process as individuals naturally interact with everyday objects in various required activities. In this project, we seek to explore specific dimensions in the IoT design space, including user control, modality, and information sharing to design sensor-based mobile platforms and tools for supporting the care team in its on-going effort to create, revise, and recreate these routines that need to be integrated into daily lives to achieve desired outcomes (i.e., staying healthy).

Information Translation for Viewpoints on Health Management

Managing health with chronic condition(s) presents challenges for individuals who have to manage various aspects of their lives according to the conditions and how their body reacts. This continuous process is likely to involve interaction with family members, neighbors, community health workers, and health professionals, who contribute their knowledge and viewpoints to help the individuals navigate through all the challenges. While having various sources of support from the social network seems beneficial, individuals with chronic conditions also have to make sense of the different and sometimes contradicting pieces of knowledge from people with different viewpoints.

Based on previous work, we come to understand that these different viewpoints are the building blocks of how individuals learn to manage lives. With this understanding, we seek to explore how we could design a video-based mobile platform for people to easily present and understand various viewpoints for managing chronic conditions such as Diabetes.

Discount Expertise Metrics for Augmenting Community Interaction

Expertise identification is important for various kinds of online and offline organizations, with practical applications such as supporting question answering, problem-solving, and team formation. Existing work has explored various data sources (e.g., self-created profiles, forum discussion, email exchanges, and work-related documents and records), but might still suffer from issues such as maintenance and the cold start problem.

In this work, we seek to explore a simple and universal measure to estimate the expertise of people based on information within their browsing history (i.e., URLs). Using developers as the target population, we demonstrate that it is possible to identify novices and experts of programming based on just two weeks of their browsing history by examining the types of programming related websites they visit.

Designing Enjoyable Training to Improve Visual-Motor Integration Ability for Preschool Children with Autism

One well-established goal of public health officials has been the early detection of developmental delays. One aspect of the delays is visual-motor integration ability, which exhibits in certain children with autism. Clinicians often use standardized tests to assess visual-motor integration ability of children, with treatment activities such as having the children clipping and pasting paper for children to practice. These activities are designed and facilitated by therapists and require professionals to observe or videotape the sessions for further analysis. The time-consuming human resource requirement makes this more extensive training/evaluation (proven to be effective in the treatment of developmental delay) almost impossible.

We designed a computer game, called CuttingGame, to approximate a standardized test in the assessment of the visual-motor integration abilities of children. By making the test a game, we created a playful experience that both assesses and trains children in visual-motor integration and does so in a natural and enjoyable way.
