From 1989 until 2017 I was on the faculty in the Department of Computer Science at the University of Texas Rio Grande Valley. My doctorate is in Psychology from the University of Houston in 1980, and I have a M. S. in Computer Science from New Mexico State University. My academic research interests center on information visualization with a focus on document retrieval, human computer interaction, and interactive systems generally. Other projects are concerned with personal information management, knowledge domain representation, and the uses of visualization across disciplines.
