My office is MEB 3470 (map). 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. 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.
office phone: +1 801 581 4280 (I strongly prefer email and rarely check my phone messages)
