My teaching areas at Colorado State University included television production, digital photography, new media technologies, documentary history & production, and telecommunication. I will teach three courses in these areas on the Spring 2025 voyage of Semester at Sea. My research is focused on the social effects of new communication technologies, primarily concerning digital television and the Internet. In March 2022, Wiley-Blackwell published the second edition of my Digital Universe: The Global Telecommunication Revolution book about the past, present, and future of the internet and other key digital communication technologies, including the effects of the diffusion of Artificial Intelligence (A.I.) on media professions and telecommunications. In June 2020, I published a new chapter on digital television in the 17th edition of the Communication Technology Update and Fundamentals text. It included research on Over-the-Top Internet-delivered video programming, and emerging 4K and 8K ultra-high-definition television technologies.
I earned my Ph.D. in Mass Communication from Indiana University in Bloomington in 1995.
