I am an emeritus professor of computer science at The George Washington University (GW). I developed the first regularly offered university course on computer security at the University of California, Berkeley in 1970.  My second book, Modern Methods for Computer Security and Privacy, published in 1977, was a standard textbook in the few computer security courses offered at the time around the world.  My other books, all anthologies, captured the state of cybersecurity and privacy at various times. 

​

 A Fellow of the Association for Computing Machinery, I institutionalized the ACM Conference on Computers, Freedom, and Privacy.  I've served on a number of Advisory Committees for government and industry.

​

I've organized  several projects that pushed forward emerging areas of cybersecurity over decades.   These included a 1987 workshop that was one of the first to explore issues related to Internet voting; a 1999 study of foreign encryption products that explored the effect of the United States export control regime on American and foreign manufacturers and produced his Congressional testimony and the display of an array of the products purchased at the time; a 2004 workshop that explored a National Cyber Security Exercise for Universities that  sparked several cybersecurity educational competitions; a 2010 workshop that articulated steps to insure that universities produce appropriately educated individuals for the cybersecurity workforce; and the development  of new courses as the field of cybersecurity grew, that focused on e-commerce security, information policy, and cybersecurity and governance.

​

I've been the thesis advisor for nine doctoral students and  project leader for a scholarship program that produced over a hundred cybersecurity experts with degrees in at least ten majors. I also serve occasionally as an expert witness and consultant, and enjoy speaking about cybersecurity, privacy, and related policy issues when my schedule permits.
