Contact

If you have a question about one of the classes I’m teaching, please use the course emails instead. These are checked by me, the co-instructors, and head TAs, so you’ll get an answer more quickly if you use them.

  • CS 61B: cs61b@
  • CS 61C: cs61c@
  • CS 161: cs161-staff@
  • CS 168: cs168@
  • CS 188: cs188@

Personal email, only if it’s not related to the courses above: peyrin@

Note: peyrin@eecs. forwards to peyrin@ so emailing either one is equivalent.

(Add berkeley.edu to the end of each email)

Writing

Sometimes I write about teaching-related things at CS 161’s pedagogy blog. (Sorry it’s dormant. I’ve been more focused on course-specific projects lately.)

Projects

Not a comprehensive list. Most of my work is contributing miscellaneous parts of courses, but here are some relatively standalone things I made.
