Welcome to the website of the 48th ACM SIGPLAN Symposium on Principles of Programming Languages (POPL 2021).
The annual Symposium on Principles of Programming Languages is a forum for the discussion of all aspects of programming languages and programming systems. Both theoretical and experimental papers are welcome, on topics ranging from formal frameworks to experience reports. We seek submissions that make principled, enduring contributions to the theory, design, understanding, implementation or application of programming languages.
POPL 2021 and its co-located events will take place in Copenhagen, Denmark, January 17–22, 2021.
