CPP spans areas of computer science, mathematics, logic, and education. CPP 2023 (https://popl23.sigplan.org/home/CPP-2023) will be held on 16-17 January 2023 and will be co-located with POPL 2023. CPP 2023 is sponsored by ACM SIGPLAN, in cooperation with ACM SIGLOG, and supported by a diverse set of industrial sponsors. Similarly to other events collocated with POPL 2023, CPP will take place as an in-person event at Boston Park Plaza, and will require attendees to provide proof of vaccination (details will be available soon). Virtual participation via Airmeet will also be available; look for updated information about that option on the POPL web site.

This support is particularly aimed at undergraduate and graduate students, postdocs, and those from marginalized groups. If you wish to apply for support you may do so by sending an email to the CPP conference co-chairs (Dmitriy Traytel and Robbert Krebbers, see below for their email addresses), with a brief description of your situation. The deadline for applications is 11 December 2022, 23:59 AoE. Notifications will be sent out at most two days later; hence, those who cannot be supported will still have the opportunity to register with the regular early registration fee before 16 December. Applications arriving after 11 December will be considered only if additional budget is remaining. CPP's student support is made possible by our generous industrial supporters: https://popl23.sigplan.org/home/CPP-2023#About ### Contact For any questions please contact the chairs: Steve Zdancewic <stevez@seas.upenn.edu> (PC co-chair) Brigitte Pientka <bpientka@cs.mcgill.ca> (PC co-chair) Robbert Krebbers <mail@robbertkrebbers.nl> (conference co-chair) Dmitriy Traytel <traytel@di.ku.dk> (conference co-chair)
