  • My GA Tech EA (see above) has full access to my GA Tech email (and calendar). If you want to send me a private email, please use my personal email address.
  • I review emails regularly. But remember, email is NOT an active form of communication. Don’t expect responses in a few minutes. Usually, expect a response within 24 hours to a few days.
  • Short emails (in text) are likely to get a quicker response. Attachments are less likely to be opened, sorry.
  • I read all emails, though thanks to SPAM, some (well, many) are missed. If a response is needed for something that has not been received, please resend it.


The phone numbers for my office are listed on the card above. When you call it, you will hear a message telling you to send me an email, I suggest you do that. You already have my mobile/cell phone number if we work together.


My FAX # at GA Tech is +1-404-385-4509. Please make sure to put my name on the cover page.
