I am an Associate Professor at the School of Information Sciences (iSchool) , the University of Pittsburgh. I also have academic affiliation with the Intelligent Systems Program, an interdisciplinary academic unit focusing on research and education on Artificial Intelligence. I am the director of a research lab called Information Retrieval, Integration and Synthesis. I was the chair of SIS Council, the governing body for the iSchool, between 2012 and 2014. I currently serve on the editorial board of SCI/SSCI indexed journals “Information Processing and Management”, “Internet Research” and “Aslib Journal of Information Management”.

Research Goals and Methodology
The goal of my research aims to advance people’s capabilities of accessing online information with the support of various cutting-edge intelligent and social information technologies. This goal fits nicely to the current data and information exploration environment, where there is too much data for people to process and consume, therefore, people need information technologies to assist them.
At the same time, I believe that the role that intelligent technologies can play is not to replace humans but rather to assist and augment humans in the access process. The relationship between humans and the technologies is a synergistic one where humans and machines work together to resolve the needs of the humans. Therefore, I am interested in making technology as enabler rather replacer, and it is people who initiate the needs of access, provide meaningful context, and utmost measures of success or failure of the technologies.
My research interests also root in the fact that I am in an information science school, where interdisciplinary and collaborative research is natural and has the greatest impact. I have built research teams and projects that involve faculty and students from different disciplines and various universities/institutions, but my goal of the research is always consistent.
My research can be summarized into two major themes. The first one is called intelligent information processing, which combines information science and computer science. Within this theme, I mainly worked on two research topics:
- intelligent information retrieval and its applications to personalization and social information access, and
- multilingual information access and its applications to interactive multilingual environment.
The second research theme is scholar data management, which combines information science and management. On this theme, my research work has been mainly on
- scholarly collaboration and research data management on modern knowledge and information infrastructure.
Major Research Projects
- Open Corpus Personalized Learning
Funded by NSF, Duration: 2015-2018
This project merges research on text analysis, human learning, and personalization to enable open corpus personalized learning.
- Teen Health Information Behavior and Social Q&A
Funded by OCLC/ALISE, Duration: 2015
This project investigates teens' assessments of the Accuracy, Credibility, and Reliability of health information in Yahoo! Answers about eating disorders. The aim is to contribute to the greater understanding of youth information behavior, health information literacy, and the role of Social Q&A in the provision of health information to young people.
- Tapping into Public Academic Information on the Social Web: Towards a Novel Academic Recommendation Framework
Funded by NSF, Duration: 2010-2012
This project aims to explore the utility of new and rapidly expanding public academic information resources on the social Web. The goal is to develop a quality assessment and an association discovery framework for online academic information, and ultimately to establish a novel framework for supporting researchers in accessing, organizing, utilizing, and exchanging all types of academic information.
- User-centric, Adaptive and Collaborative Information Filtering
Funded by NSF, Duration: 2007-2012, Partner: CMU CLAIR group
Working with our CMU partner, the objective of this project is to develop new technologies for Adaptive Filtering (AF) -- the problem of learning and adapting to a user's information needs "on-the-fly". We propose a new framework called "Enriched Vector Space Model" (EVSM) that allows a rich representation of user's interests in terms of queries, entities (person names, locations, dates), topical categories (politics, crime, economics), implicit and explicit feedback received from the user. Such user profiles can be used to perform more intelligent and personalized information filtering for each user.
- Adaptive, Robust, and Distilled Information Access
Funded by DARPA GALE Program, Duration: 2005-2007.
We propose to develop and demonstrate an integrated set of techniques for building an adaptive, robust and distilled information access module for information distillation, which is able to handle electronic newswire, transcriptions from broadcast news, telephone conversations, and talk shows, and web documents from newsgroups and weblogs, no matter whether they are originally in English or in Chinese, Arabic or surprise languages.
- Digital Library for Learning Digital Library
Funded by University of Pittsburgh, Provost's Innovation in Teaching Award. Duration: 2005-2006.
This project designed and developed an interactive, integrated and active learning environment using digital library technologies, with the goals to improve the quality of the student's learning experience and increase the effectiveness of that experience.
I view teaching as a communication of knowledge and ideas between the teacher and students. A successful teaching session needs careful thinking, imaginative designing, clear presentation, and frequent evaluation and updating.
