Research Areas

My ongoing study of the interaction between users and the library research tools has led to development of innovative ways to ensure technology is meeting patrons’ information needs. My past projects have included building search widgets, co-developing a homegrown system for creating online research guides, and the production of multimedia content.  My research interests include point-of-need information services, e-learning, mobile technologies, and web metrics.  I am also interested in the search process and developing ways to improve existing search tools to better meet the need of our students, faculty and staff.
