University of Chicago Programming Languages Reading Group University of Chicago Programming Languages Reading GroupThe Programming Languages Reading Group, part of PL research at UChicago, is an occasional, informal meeting to discuss interesting PL papers. Food is provided. Visitors welcome!
To receive announcements, join the Slack channel.
We also have a mailing list that you can sign up for here: pl-readinggroup.
To suggest a paper, add the topic and any links to the Google Doc.
For Fall 2024, PLRG meets on Fridays 12pm in Crerar 236.

For the Spring 2020 term, PLRG meets on Wednesdays, 3:00pm at https://uchicago.zoom.us/j/564109413.
Reading group did not meet for the Fall 2019 term and Winter 2020 terms because everybody was distracted.
For the Spring 2019 term, PLRG met on Tuesdays, 3:00pm in Crerar 236.
Reading group did not meet for the Fall 2018 term, because of Stu’s “The Little Typer” Seminar, John’s Coq Seminar, and paper deadlines. Winter 2018 was also skipped because nobody was thinking about PLRG.
For the Summer 2018 term, we met on Fridays at various times and places.
