Contact Michael

If you want to contact me, the best way is by e-mail. I also respond on Twitter, but technical or professional conversations there tend to quickly outgrow 140 characters (and I prefer e-mail to TwitterDMs).

If you are a student in Introduction to Recommender Systems on Coursera looking for course support, please ask questions in the Coursera discussion boards.

If you are a prospective student looking to work in my group, please see my students page, tips for writing a good e-mail, and FAQ.

If you want to write to me about personal things (non-academic, related to my personal programming projects, etc.), use my personal address. Please do not write to my personal address about classes, my research papers, or LensKit.

On most services, I am mdekstrand or occasionally elehack.

If you are a student looking for work, please see my student openings.

Office Hours

My office hours for Spring 2020 are the following:

  • Tuesdays 10:30-11:30 p.m.
  • Tuesdays and Thursdays 3–4 p.m.

All office hours are in CCP 255 (at 777 Main St.).

Social Media Connections

I invite everyone to follow me on Twitter or Mastodon. Please don’t expect me to automatically follow back, or if I follow you to keep following forever; I optimize my twitter feed to provide a personally useful blend of information, and there are many interesting people I do not follow. If you are a student in one of my classes, I will not follow you until the class is over.

I also welcome LinkedIn connections. If you want to connect with me on LinkedIn, please say something personalized (even if it is just a brief sentence); if we have met in person or communicated on other forums, mentioning those is good.
