My research interests range broadly in end-user programming environments, with particular focus on database accessibility and analysis, and scientific visualization. I have pursued those interests through research projects in the field of bioinformatics, wherein the end-users are scientists (untrained as programmers or IT professionals) who need to analyze large quantities of complex data. In particular, I have been interested in developing and studying the use of software tools that will allow such end-users to use powerful information technology to enhance their research, without the need for traditional programming training.
