Fall 2025 office hours for Ryan Calder (Mondays 12:30p–2:30p, Mergenthaler 435)
- Mergenthaler 435. Knock at your start time to let me know you've arrived, even if you hear someone inside. - Please sign up no later than 12:15p on the Monday you plan to attend. - Grad students may sign up for one or two slots per week. Undergrads may sign up for one slot per week (unless you come as a pair—then one or two). - Only sign up for EMPTY SLOTS unless you have the permission of the person(s) already in the slot to let you join. - Undergrads: If you can't make it Mondays 12:30p–2:30p or if all slots for the week are taken, contact your TA to set up time with them. If you and your TA can't find a time, you may meet with another TA—but not more than twice a semester for a given TA who is not your own.
