In particular, I am interested in examining how and how well laypeople learn about health-related knowledge in parallel with the health information seeking process through web search. It has long been understood that knowledge acquisition is an important component in the information seeking process. Further, empirical studies have demonstrated that learning is a common phenomenon in information seeking. However, for users, especially laypeople, who must gain knowledge through their interactions with a search engine, the current general-purpose search engine does not sufficiently support learning through search. Health information seeking (HIS, hereafter) is a domain-specific search, where users who possess higher knowledge tend to have better strategies and performances in solving their search tasks. While learning clearly plays an important role in the HIS process, there has been little research in this area. Little is known about the factors that might enhance or impede such learning during online HIS. Therefore, this project aims at examining health consumers, especially laypeople's search as learning behaviors and performances. A mixed method design is adopted, consisting of experimental-based studies and interviews. So far, we have conducted 24

- Results of the interview have been submitted to a conference and under review.
- Another work predicting the learning performance based on search behaviors is in preparation.
Another research interest of mine is to explore different methods or frameworks that can be applied to the analysis of human's interaction with websites. It is common to study user behavior based on log analysis. Most previous studies, however, heavily rely on search logs. The problem is that search log analysis, consisting of the analysis of users’ terms, queries, and sessions, is only applicable to examine the usage of web search engines. Clickstream data offers an unobtrusive data source for understanding web users’ information behavior beyond searching. However, it remains underutilized due to the lack of structured analysis procedures. Based on our experience from two case studies with clickstream data analysis, we integrated and proposed an analysis framework. Overall, the integrated analysis framework is designed to be independent of any specific research settings so that it can be easily adopted for different clickstream datasets and research questions.

As the research assistant of the Youth Data Literacy project , I assisted and led workshops, interviews and observations with teens and staffs at seven branches of the Carnegie Library of Pittsburgh to examine teen data literacy practices and design for appealing data environment. I also led a subproject, exploring the interplay between teens’ Affective states (A), Behavioral states (B), and Cognitive states (C) in relation to the personal data they generate in social media, applying the “ABC model” from the social psychology domain. Given the results, we suggest librarians, educators and software developers apply a range of strategies in reaction to teens’ different ABC states to the design of data literacy programs, services, and software applications.
