Dr. Geoffrey Z. Liu
Associate Professor

Statement of Research Interests & Experience

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 Areas

• 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
