How to reach me

Teaching

Please visit the PANDA page of the course you are enrolled in, then use either

  • the forum (any time),
  • the anonymous question or feedback form (any time), or
  • the chat (time slots announced there).

I'm subscribed to all course forums and feedback forms, so will be notified as soon as you ask a question there.

E-Mail

  • sommer@cms-labs.org (PGP public key)
  • Enrolled in a course with me? Please use PANDA (see above) instead of sending an e-mail if you can.
  • If you received an e-mail from a gmail.com address (cmacleod.uvic.ca@gmail.com, professorsmail69@gmail.com, or similar) claiming to be me and asking for an urgent favor (“Please I need your assistance urgently”, “I need a favor from you right now”, or similar), you are witnessing an attempted scam. Please see, e.g., the E-Mail Alert page of Brown University for how the scammer is likely intending to continue.
