Call for Workshops and Co-located Events


                    POPL 2022

      49th ACM SIGPLAN-SIGACT Symposium on
      Principles of Programming Languages

             Sun 16 - Fri 21, January 2022 
      Philadelphia, Pennsylvania, United States


The 49th ACM SIGPLAN-SIGACT Symposium on Principles of Programming Languages (POPL 2022) will be held in Philadelphia, PA, United States

POPL provides a forum for the discussion of fundamental principles and important innovations in the design, definition, analysis, transformation, implementation and verification of programming languages, programming systems, and programming abstractions.

Events focusing on experimental and theoretical topics are welcome.

Proposals are invited for workshops and other events to be co-located with POPL 2022.

Workshops should be more informal and focused than POPL itself, include sessions that enable interaction among the workshop attendees. The preference is for one-day workshops, but other schedules can also be considered.

Dealing with the Effects of the COVID-19 Pandemic

The planning for POPL 2022 is in a flux due to the global COVID-19 pandemic, and in particular, the format of the conference may be a physical, virtual, or hybrid physical/virtual meeting. The decision regarding POPL’22 format will in turn determine the format of the workshops.

The workshop proposals should describe plans for remote participation and in particular indicate

  • if the organizers are committing to opening the workshop to remote participation and
  • whether the workshop will take place in the event that there will not be an in-person POPL.

Advice and resources for enabling remote participation are available at
