Dear colleague, As you may know, FSTTCS 2025 (https://www.fsttcs.org.in/2025/) is going to be held at BITS Pilani, K K Birla Goa Campus (https://www.bits-pilani.ac.in/goa/) during December 17 – 19, 2025. The conference is organized by IARCS, the Indian Association for Research in Computing Science (https://www.iarcs.org.in/), in association with ACM India (https://india.acm.org/). It is a very visible forum for presenting original results in foundational aspects of Computer Science and Software Technology. As in the previous years, this year too, co-located with the main FSTTCS conference, IARCS is organizing the Workshop on Research Highlights in Programming Languages (RHPL@FSTTCS). The focus of the workshop will be on all areas of Programming Languages (PL), including but not limited to: - Applied formal methods - Automated and interactive theorem provers - Compilers - Concurrency and memory models - Domain and type theories - Program analysis and verification - Program sketching, synthesis and repair - Programming language design and semantics Further, in view of the increasing role of Artificial Intelligence (AI) and Machine Learning (ML) in PL theory and practice, the workshop also includes in its scope themes pertaining to the influences of AI/ML concepts and tools on the mentioned PL topics, and vice-versa; for instance, probabilistic programming languages. The website for the workshop is: https://fmindia.cmi.ac.in/rhpl2025/ The objective of RHPL is to foster interactions between the attendees of the workshop, and more broadly between researchers working on Programming Languages and the traditional FSTTCS community of researchers working on Theoretical Computer Science and Formal Methods. We solicit: (1) Talk proposals: On recent work that has been published in good venues, or is mature in terms of approach and evaluation. (2) Poster proposals: On early ideas that are promising but have not been developed fully. Selections of these proposals will be made based on the promise of research possibilities and their novelty. Proposals to the workshop can be based on one or more works, published or unpublished. They may be submitted using the Google form below. https://forms.gle/RufuAs54zxsadp1n7 The important dates for the workshop are as below. All dates are in Indian Standard Time (IST). - Submission portal opens: July 28, 2025 - Submission deadline: September 18, 2025 - Notification: September 25, 2025 - Early registration deadline: TBA - RHPL@FSTTCS: TBA We look forward to receiving your talk/poster proposals to the workshop.
