Students: My office is MEB 3470. Free free to drop in any time my door's open. If I'm too busy to talk I'll let you know, and we'll find a different time.
I travel a lot. If you're having trouble finding me, it's possible that I'm out of town. Drop me an email and we can sort things out.
Most mornings I try to get some class prep and research done from outside the office, so I'm not generally available until late morning.
