The overarching theme of my informatics interest ties closely to the marriage of science of care and science of data, with a focus on bridging the gap between population-level evidence and individual patient need. The recent rise of consumer health awareness and the increasing availability of pervasive health technologies have offered new promise to advance precision health research, to better inform patient communication and shared decision making, and to improve patient activation and engagement. The key is to transform the accumulated patient-generated health data (i.e., PGHD) and N-of-1 personal health data (i.e., “small data”) into actionable insights that can enable dynamic evidence delivery to meet patients where they are.
However, the vision has incurred multi-level challenges.
First, the patients’ care team members need to be able to manage rapidly increasing amounts of patient-generated data. Therefore, consumer health information management and analytics tools are needed to filter noisy and irrelevant data, identify insights from multi-layer query and present the minimal description for the care team based on patients’ need in different contexts.
Second, new patient engagement and behavioral change platforms and tools are needed to facilitate patients themselves to understand their own health/wellness status, disease inflection points and progression patterns.
Last but not least, new policy initiatives and data/research network, as an incentive and safeguard mechanism, are needed to increase the interoperability of consumer health data.
My research thus lies on the intersection of these challenges and the development of a cognitive learning framework that can leverage PGHD and self-experimentation to induce patient engagement and intervention adaptation strategies. First, how to assess applicability and adapt population-level evidence to an individual level? Second, with all the added nuances and patient preferences uncovered in the sequential observations of PGHD, can we generate feedback for users to make sense of their data, or capture individual predictive pathways that can help infer patient need for their care team? Finally, by combining multiple N-of-1 sequential observations, how to perform meta-analytics and infer best practice strategies as the basis of collective real-world evidence? At the individual level, how to leverage such insights on best practice to further break down an overarching goal into a series of smaller actionable tasks for individuals to implement in intermediate stages?
To fully capture the benefits of interpreting patient need, these are the questions we need to address. In some cases where we don’t have enough personal health data to infer patient status and preferences, we need to establish an active self-learning mechanism to interactively guide users through a self-experimentation process similar to what N-of-1 trials are attempting to achieve. The ultimate goal is to optimize the tailoring of care plans based on the ideographic understanding of patients so as to bridge the gap between population-level evidence and best practice in real-world evidence from PGHD in an interactive manner. Additional benefits include enabling healthcare professionals and care team to think “outside-of-the box” when trying to find an alternative solution to combat treatment adherence issues.
This investigation can also enable us to start collecting evidence on best practice strategies for further investigation. One direction is to produce innovative approaches of computing personalization and incorporating personalization analytics into service design. In the healthcare domain, I am working on active characterization of personal wellness status and active recommendation that are driven by outcome prediction. The importance of personalization research and system design arises from the need of serving the long tail of user need. While many multi-year structured programs have verified the effectiveness of individualized intervention on preventive care and chronic disease management (Helmrich et al, 1991; Bailey, 2001; Finland National Type II Diabetes Prevention Programme, 2007; CDC Diabetes Prevention Program, 2008), the task of offering personalized services dynamically in users’ context has posed grand challenges to existing service providers. On the one hand, integrated care models have shown promises in satisfying the long tail of demand. On the other hand, the success of an integrated model in clinical trials is not enough to secure a disruption in the service market. In fact, its reliance on the constant updates of user wellness status and tailoring of intervention accordingly requires solid system support from both the vendors and system operators. Some key competencies to be provided include: (1) inferring risks from multiple heterogeneous sources (and whenever necessary, going back to the user and care team to solicit for more information); (2) handling multi-faceted risk stratification; and (3) “on the fly” assessment and recommendation with respect to trends shown in the incoming data stream. During the process of data analytics, I am also quite interested in using social signals to improve compliance feedback strategy.
I am involved in the development of an evidence-based wellness management platform in a cloud computing environment. The platform provides an API for healthcare applications to (i) integrate information from heterogeneous data source (Sense), (ii) draw predictions by applying or extending models in a repository (Predict), and (iii) trigger proper responses (Respond). The development side of goal is to enable any independent software vendor (ISV) to use the API and the Sense-Predict-Respond framework to implement their services and exchange information with 3rd party applications.

Overarching Theme & Previous Work
The overarching them of my research interest ties closely to the marriage of artificial intelligence and human computer interaction, with a focus on integrating machine learning and empirical analysis approaches for natural language understanding. My previous research concerns the development of spoken language understanding applications in spontaneous speech, using a variety of approaches ranging from statistical analysis, empirical study to machine learning. This is no secret that people speak differently under different circumstances. Some of the differences are systematic and can be attributed to deeper differences, such as the intention of speaker.
My contribution to this problem is to develop a learning framework that can be used to identify multimodal features (and patterns) that are characteristics of the systematic differences in human conversations and to build automatic detection mechanisms that are robust to spontaneous speech effects. Current projects include automatic topic segmentation and labeling and automatic decision detection. The overarching goal is to provide visual aids at the right level of details for the users to find information from the often-lengthy archives of conversation recordings.
