Welcome to the first and longest running website maintained by a professor at Georgetown University. I am the Founding Director of Georgetown's Communication, Culture & Technology Program (CCT), and have been a professor at Georgetown for 30 years. I set up the first website at Georgetown in 1993, and began developing websites for courses in 1994. When I launched the CCT Program in 1995-96, I began developing custom-designed sites for each course with web syllabi, readings, and lecture notes, and this site has now become my archive of courses, lectures, essays, and presentations for students and those interested in the fields I work in.

My teaching and research interests span several fields and disciplines: theory and philosophy of technology and culture; semiotics, linguistics, and philosophy of language; computation and symbolic cognition; media and communication theory and history; art theory and history; and intersections in art, music, film, and visual culture.

This site provides links to my course syllabi, lectures and presentations, and published work for use by all students and anyone interested in my various projects.

I now maintain Wordpress sites for student seminar work (after years of managing a Seminar Wiki site). This platform enables student discussions and contributions to the real-time knowledge-building purpose of seminars in a peer-dialog context, and allows students to publish rich-content essays and final research projects. Student work is accessible on the Web, indexed by Google and other Web indexing sites. The platform provides a fixed URL for reference and use by students in future professional work.

Recent seminar sites for student work:

• CCTP-820: Leading by Design – Principles of Technical and Social Systems (Fall 2015)
