Visualization of a design as presented by our experimental design explorer. My recent work is on building computer-based tools that support expert work—tasks that require expert knowledge and involve finding creative solutions to ill-structured problems, like design and writing. My doctoral dissertation presents and evaluates a set of design principles for building tools that support expert work.

A shorter introduction to this work can be found in:

C. G. Jennings, A. E. Kirkpatrick, and P. Mohseni. Supporting expert work processes. In P. Barker and P. van Schaik, editors, Electronic Performance Support: Using Digital Technology to Enhance Human Ability, pages 249–262. Gower, 2010.

One of the prototype systems built as part of this work is XDS, a tool that supports the design of ANOVA experiments. Some demonstration videos of XDS in use (QuickTime format):

    A Brief Exploration Session (17.8 MB)

Another interest is developing better evaluation methods for broad-scoped research in human-computer interaction. This work draws on other domains for its inspiration, including legal practice, medicine, and philosophy. An introduction can be found in my doctoral dissertation.

Besides human-computer interaction, I have also worked in stringology. For more information, see the Franek-Jennings-Smyth exact pattern matching algorithm.

What's with the [?] Icon?

You may notice this icon sprinkled throughout this site, just in front of some links.  It means that the link will do a Web search for terms appropriate to the highlighted text.  I do this for items that I feel an interested reader might want more information about—not because I'm too lazy to find a good page to link to, but because I'm too lazy to continually find new links as old ones go stale.  Besides, this way you get a pointer to a lot more information than one page would hold.
