After getting a BA in Biology at Rice University (1968), I went directly to graduate school at the University of Texas at Austin, finishing with a PhD in Computer Science (1971). My first full faculty position was in Computer Science at Rutgers University, for three years. I then became a Principal Scientist at Bolt Beranek and Newman (BBN) in Cambridge, Massachusetts for 16 years. This was a high-tech, research firm, where I observed a lot of early Internet development.
In 1990, I moved to the University of Illinois, where I taught in Curriculum & Instruction, with appointments in Bioengineering, the Center for Writing Studies, and the Center for East Asian & Pacific Studies. After ten years I switched my primary appointment to Information Sciences. During 2007-08, I held a Fulbright Distinguished Chair at the National College of Ireland in Dublin. Over the years, I’ve taught courses in Australia, Finland, Sweden, Turkey, Germany, and Nepal.
I am now a Professor Emeritus in Information Sciences at the University of Illinois at Urbana-Champaign (UIUC).
