My walk-in (no appointment needed) office hours this semester are Mondays, 1-2:30 pm, 2610 CL.
Since this Monday is Labor Day and the university is closed, I will have a special make-up walk-in hour, 12:30-1:30 pm, on Wednesday.
As always, feel free to e-mail to set up an appointment if you can't make the Monday 1-2:30 time and you need to see me.
