Email is by far the quickest way of contacting me — my address is c.novakovic@cs.bham.ac.uk.
If you're an undergraduate or taught-postgraduate student and are emailing me about something teaching-related, the School usually requires you to do this from your School/University email address rather than from Gmail, Hotmail or another free email provider (whose emails I don't always receive!).
If your email is particularly confidential, you might want to encrypt it using PGP before sending it to me. My PGP key appears here when you're viewing the secure version of this page.
In person
My office is room 117 in the School of Computer Science (building Y9 on the University's Edgbaston campus map). I have lots of research and teaching commitments, so please let me know in advance if you want to meet.

I can also be contacted by telephone or fax, and I'm probably reachable by Skype sometimes too — please ask for the relevant details.
