I have been retired since September 2008, but continue to do mischief as an Adjunct Professor with occasional teaching and funded research projects. My latest project is the second edition of my book cited above.
My research interests include computer internetworking systems, especially time synchronization technology. I have participated since 1977 in Internet technology development. My sponsors induce the National Science Foundation (NSF), Defense Advanced Research Projects Agency (DARPA), US Navy, US Army and NASA Jet Propulsion Laboratory.
I teach graduate courses in computer networks, computer security and the mathematics of cryptography. I also teach undergraduate courses in computer architecture, electronic circuit analysis and analog/digital communications.
I am a member of the National Academy of Engineering and a Fellow in the Institute of Electrical and Electronics Engineers (IEEE) and the Association for Computing Machinery (ACM).
