Different Office Hours

For a various reasons, I need to change my office hours for the next few weeks. Rather than the usual Friday office hours, I'll hold them on Thursday April 2nd, Monday April 6th, Monday April 13th, and Thursday April 23rd, all from 1-3PM. I'll have other times available by appointment. Sorry about this: just turns out that Fridays are getting quite complicated for me for the foreseeable future.
