The Georgetown directory has my email address and office phone number. Be aware that as a telecom geek, the office phone will try to find me wherever I am. Be mindful if you are calling at midnight. Likewise, if it is mid-day in Washington, it is midnight in Beijing.

Unless the sky is falling, I am unresponsive Friday afternoon through Sunday. If the sky is falling, send an urgent email. Otherwise, I’ll get back to you Sunday or Monday. If you are asking for money, make sure your interests match my funded research interests. If you are selling stuff, I don’t buy much stuff. If you want to fund research, please contact me. While I am serving in the Federal government, I will be unable to discuss funding opportunities. If you wish to fund the Cyber SMART or other efforts at Georgetown, contact Clare Sullivan.

If you want to come work for me at Georgetown as a student, postdoc, or research scientist/faculty, read this page carefully.
