Research
My research interests lie in the broad
categories of human-computer interaction, information
and knowledge management, and digital libraries.
My work is unified by an interest in how people find, refind,
and reuse information and how technology can help support
these tasks.
Recently, I have been exploring aspects of personal information
management (PIM), interfaces to information, information archiving,
and voice user interfaces (VUIs).

ResultsSpace Project
ResultsSpace is a 3-year, NSF-funded project on which I co-authored the grant proposal.
The project focuses on developing architectures and interfaces to support mutli-session,
exploratory, and collaborative search.

Personal Information Management
People encounter large amounts of electronic information on
a daily basis. Emails, web pages, pictures, multimedia,
and other documents require storage, organization, and
mechanisms for sharing and reuse. Information can easily
become fragmented across multiple computers and
devices and it is not always apparent what version
of a document is most up-to-date.
The study of Personal Information Management (PIM) focuses
on how people organize, store, manage, and reuse the array
of electronic information that has become commonplace in
today's home and workplace. My
Ph.D. dissertation research
focused on factors that affect how people
refind information on the web that they have seen
before.
I was a co-organizer for the
2006
and
2008
workshops on Personal Information Management.
These workshops were both huge
successes, drawing researchers from a variety of disciplines
and interest areas.
Voice User Interfaces
For five years, I worked as a member of the research and
development labs of SBC Communications (now merged with AT&T)
in their Speech and Language Technology Group.
I worked on the evaluation and development of voice user
interface technologies and continue this interest.
I am especially interested in how voice interfaces can be
used to help
many populations of users gain access to information and
have explored aspects of this in research with the
Dialoge Research Group at Virginia Tech.
We examined
structures present in many HTML web pages
and developed an annotation scheme to assist in
transcoding HTML web pages into VoiceXML.
I also explored interfaces for
voice retrieval of information
previously seen on the web.
