My research and teaching span information retrieval, human-computer interaction,
information seeking and use, scholarly communication, and bibliometrics. Since the latter
1990s, these themes have converged in the study of data and data practices, exploring how
observations, models, artifacts, and software become data; how these practices vary by
individual and by discipline; and how these findings can be employed in the design of
data collection, data management, data archiving, and science policy. 

Publications remain the currency of scholarship, despite substantial evolution in form
and function over a period of centuries. In the latter 20th century, data began to be
viewed as scholarly products in their own right. Factors contributing to the value of
research data include the transition from print to electronic publishing, the ability to
acquire and analyze large volumes of digital content in the sciences and humanities
alike, and policies that promote openness and transparency. 

On the surface, open access to data appears to offer vast benefits for research,
education, and innovation by leveraging public investments in research. Public policy
documents suggest that releasing data is an easy task to be accomplished at the time of
publishing articles or books, and that research data are yet another genre to be absorbed
by libraries and archives. Underlying these simple claims is a morass of theoretical,
social, policy, and practical problems. This morass has proven to be fertile ground for
research in information studies. 

How to use this site: 

This site contains entries for most of my publications, presentations, and course
syllabi. As governed by copyright agreements, entries may include final published
versions, submitted versions, working documents, slides, abstracts, and metadata. Links
to sources and to video recordings of presentations also are provided. 

As most of my works cover multiple topics, the elaborate subject classification has been
abandoned in favor of listing entries by format in reverse chronological order. Each
entry has subject categories and topical tags (data, scholarly communication, information
retrieval, bibliometrics, sensor networks, astronomy, humanities, and so on) that are
searchable in the box at the bottom right of the page. Other links at the right lead to
my UCLA homepage, research group, blog, Twitter feed, and email. 

The site is updated regularly with new publications, presentations, and other works.
