Teaching

Winter 2020

Office Hours (Skye 259)

  • Wednesday, 3–5 pm
  • Thursday, 10–11 am
  • Friday, 2–3 pm

My Wednesday office hours are primarily for students in Math 151B, while the Thursday and Friday office hours are primarily for students in 146B. Those students will be given priority at those times, though everyone is welcome to attend.

NB: I will be out of town from 14 January until 19 January. There will be no office hours on those days, but your discussion sections will still meet, and homework is still due as usual.
