I have a strong research background in information retrieval and systems engineering. I am currently investigating cognitive shifting in dynamic information retrieval. I have also developed a strong research interest in school libraries serving local communities, from my involvements with the Evergreen Education Foundation and its school library projects in China.
Possible PhD Thesis Topic Area
Information retrieval systems and algorithm design
Behavioral and cognitive aspects of interactive information retrieval
Computer-mediated interaction and communication
School libraries and community service in developing countries
