Research Description
My current research projects focus on supporting dependability in end-user programming. I have also worked quite a bit on how to scale up declarative visual programming languages to support realistic programming. The results of the work to date in this direction have been implemented in the Forms/3 and FAR visual programming languages.

I've spent most of my time recently taking a serious look at software engineering aspects of end-user programming. The objective is to improve the dependability of software produced by end-user programming languages. This project is funded by the NSF ITR program. This work has grown and combined with that of other researchers to form the new EUSES Consortium (End Users Shaping Effective Software), which is a group of researchers from Oregon State University, Cambridge University (UK), Carnegie Mellon University, Drexel University, Penn State University, and University of Nebraska working together on this problem.


Applications of Research
The software industry is starting to show an intense interest in developing new dependability mechanisms for commercial products that are aimed at supporting end-user programming.
