I'm originally from Baltimore, Maryland. I got my undergraduate degree in electrical engineering from Cornell University in 1978, and a Masters degree in electrical engineering from Carnegie Mellon University courtesy of the Bell Labs One Year On Campus program.

I'm also an alumnus of Bell Labs in Naperville IL and Murray Hill NJ, and of Bellcore (now Telcordia) in Morristown, NJ. I worked my way through college as a broadcast engineer at Maryland Public Television.

I now work in the Office of the Chief Scientist at Qualcomm in San Diego, California. Since high school I've been a radio amateur. I started with callsign WN3RVL in 1971 and got KA9Q in 1980 while living in Illinois. I became active in amateur packet radio in the early 1980s, and this led me to what I'm probably best known for, writing a TCP/IP (Internet) package for the PC way back in the mid 1980s, though it's completely obsolete now. I've also been involved in AMSAT as a technical volunteer, and professionally in the Internet Engineering Task Force (IETF).

More recently I've been writing open source software for forward error correction and digital signal processing, and contribute to various Wikipedia articles on computer networking and communications.

Ham radio gave me my start in communications way back in high school, and I credit it with launching me on my career in computer networking and radio communications.

I've been happily married to my wife Kimberly since 2000. We live with two cats and a dog.
