Research Interests
Generally, I am interested in information technologies and systems for human-centered information processing activities (at individual, group and organizational levels). More specifically, I have the following related interests:
- Information design: preparing information so people
can use it with efficiency and effectiveness.
- Information architecture and information seeking: information architecture studies how information/content are organized in a way to best serve human's information need. It at least includes information organization and user interaction/interface design.
- Information visualization: focused on visualizations of quantitative data, information, and knowledge that facilitates human understanding in various information processing tasks.
- Business intelligence
- Visual information exploration/mining: the visual exploration process is an interactive exploration process between humans and computer created visualizations. The process is based on visualizations but also emphasizes on the human's capability of sense-making in information seeking and decision making.
- Digital dashboard: designing easy to use and easy to understand visualizations to support quick sense making and decision making at a higher level.
- Web information systems and development:
various types of web-based information systems and applications for
organizations, businesses and communities.
- Web (site) engineering: methodologies, techniques and technologies for web site planning, development, management and evolvement.
- Web-based information system architecture: the structure and architecture of web based information systems/sites; including various web application frameworks, portal, service oriented architecture, integration, etc.
- System usability: usability (ease of use) issues in various applications.
- Design science research in information system and technology (DESRIST): design is creation of the new (system, algorithm, application, methodology, technique, etc.); design research in information systems is to generate new knowledge (design knowledge) through the process of designing information systems (IT artifacts) to address human or organization problems. It is an important research phase in the information systems research cycle (as opposed to the explanation research and descriptive research).
- Applications domains and other related interests
- Knowledge management system: systems that facilitate the recording, sharing and use of various forms of human knowledge, which can be seen as an expansion of business intelligence.
- Educational technology and system: information systems that facilitates learning (e-learning), course management, and student engagement.
- Information behavior: understanding human's information processing behavior is the foundation for designing good information seeking systems, visual exploration systems, and business intelligence system.
- Information security: focusing on a particular distributed and federated system (Trusted Query Network) that can share useful information while protecting member data privacy and security.
