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 over 30 years. I set up the first website at Georgetown, The Labyrinth -- and the first website in the humanities -- 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 anyone interested in the fields I work in.

My teaching and research interests span several fields and disciplines: theory and philosophy of technology and culture; the history and theory of computation and the design of computing systems; semiotic theory and C. S. Peirce; linguistics and philosophy of language; media and communication theory and history; and philosophy and intellectual history more broadly. I also have a deep interest in art theory and history, and have worked with many artists and musicians.

Current Research Interests:

I continually draw from my earlier background in classical and medieval languages, literature, and philosophy, and have been working on new translations of writings by Leibniz (in Latin and French) on semiotics, computation, calculating machines and the binary number system. (Results of this research will appear in forthcoming papers and a book in progress.)

Over the past 8 years, I have been working on the unpublished papers of C. S. Peirce on logic, semeiotic, his designs for scientific instruments, logic machines, mathematics, notation systems, and his extensive work on the binary number system. I have a book in progress on a new intellectual history of computing and information from Leibniz to the present with a Peircean "Logic as Semeiotic" framework.

Research Resource Site: C. S. Peirce's Logic as Semeiotic Project (c.1896-1913)

• This site makes available my research on the Peirce Papers collection archived at Houghton Library, Harvard University, for my book project. I have been focusing on the unpublished papers (drafts, letters, notebooks) from the 1890s-1912. There is a link to my spreadsheet (of nearly 1,000 sources. This contains brief notes and dates of the papers for a clear picture of the trajectory of Peirce's work on logic, semiotics, mathematics, computation, and designs for technical instruments, including the many papers and notes on his methods for binary (base 2) computation, which he developed in great detail several decades before the beginnings of our digital computing era.
