Mark Stefik

Mark Stefik is a research fellow at PARC and currently manages the TAO area: Theory and Technology for Agile Organizations in the Intelligent Systems Lab. He also leads the Enforce project at PARC, which is developing an example of what he calls a “digital nervous system.”

Mark's earlier work focused on personalized news, sense making systems, hardware and software for collaboration in electronic meetings, object-oriented programming systems, and knowledge systems. Mark has contributed to several PARC spinouts. His seminal digital property rights laid the technical foundations for secure distribution for digital media including music, movies, books, and other things. Mark has over 90 patents and 200 publications. He has authored five books, including Breakthrough: Stories and Strategies for Radical Innovation from The MIT Press.

His Ph.D. work at Stanford University was on experiment planning in molecular genetics. He is a Fellow of the American Association for Artificial Intelligence (AAAI) and American Association for the Advancement of Science (AAAS).  More on his interests can be found at his personal web site.
