We are hiring! Suzanne Embury and I are looking for a talented Ph.D. student 👩‍🎓👨‍🎓 to join an exciting, high-impact project on automated testing and bug fixing of Formal Methods tools. www.findaphd.com/phds/project...

Gaetano's paper on Scaling Security Testing by Adressing the Reachability Gap has been accepted at #ICSE26! 📝 gpsapia.github.io/files/ICSE_2... 🧑‍💻 github.com/GPSapia/Reac... How to scale automatic security testing to arbitrary systems?

Had a blast at my first Google Summer of Code (GSoC) Mentor Summit. My personal highlight was speaking with the developers of many important open-source projects and learning about the various challenges they face. Hopefully, we can help address some of those with our research.

We finished the second @icfp-conference.bsky.social/SPLASH hike! We spotted multiple crocodiles, lizards, macaques, mudskippers, various fishes (e.g., archerfish and halfbeaks), birds (hornbills, kingfishers, herons, and egrets), bats, and snakes (oriental whip snake and some a king cobra).

Super excited by the SPLASH ACM Student Research Competition (SRC) results! @junwenan.bsky.social won the gold medal in the graduate category, while Emily Ong won in the undergraduate category! By the way, Junwen is looking for summer internship positions.

A reminder that we will have another @icfp-conference.bsky.social/SPLASH nature walk planned for tomorrow. Consider joining if you are (still) in Singapore! 2025.splashcon.org/attending/ou...

@ilyasergey.bsky.social awarded The Most Bendable SPLASH/ICFP General Chair award for the largest and most successful combined SPLASH/OOPSLA/ICFP ever held over the past seven days in Singapore!

It seems the first hike as part of @icfp-conference.bsky.social/SPLASH went well! A shoutout to @ningkeli.bsky.social and Yibo DONG (as well as my wife, Ting), who guided the participants on this walk. I could unfortunately not participate, as I had to travel abroad due to an urgent issue.

I am thrilled to announce Velvet: a new foundational multi-modal verifier for imperative programs in Lean. Velvet unifies execution, testing, automated and interactive proofs; and is itself proven sound. 💻 github.com/verse-lab/loom 📄 verse-lab.github.io/papers/loom-...

One week until ICFP/SPLASH’25! conf.researchr.org/home/icfp-sp...

First Day: A New Chapter at the JKU It's Wednesday. Is this important? It's my first day in a new position. So, perhaps the real question is: what's going to be important to me from now on? stefan-marr.de/2025/10/firs...

Excited to announce that the Fray paper has been accepted to OOPSLA'25! Work led by @aoli.al with a full pastalab.org collaboration. 📄: rohan.padhye.org/files/fray-o... 💻: github.com/cmu-pasta/fray 🎥: www.youtube.com/watch?v=AX6P...

I will be organizing two nature walks for ICFP/SPLASH (‪@icfp-conference.bsky.social‬)! I did one of them this weekend and was very lucky to see 11 saltwater crocodiles (including a tiny baby one), countless monitor lizards, otters, macaques, fruit bats, various kinds of birds, and fish.

Already registered for SPLASH or @icfp-conference.bsky.social? If not, check out our list of accepted papers: conf.researchr.org/home/icfp-sp... It's language implementation techniques, from debugging and JIT compiling on microcontrollers to visualizing execution patterns between CPU and GPU!

25 years of delta debugging! On this day in 2000, I presented “Simplifying Failure-Inducing Inputs” at ISSTA - now one of the most influential works in the 50-year history of Transactions on Software Engineering. Read all about its genesis and impact at doi.ieeecomputersociety.org/10.1109/TSE....

Do it for science!

Can we statistically estimate how likely an LLM-generated program is correct w/o knowing what is a correct program for that task? Sounds impossible-but it's actually really simple. In fact, our measure of "correctness" called incoherence can be estimated (PAC guarantees). arxiv.org/abs/2507.00057

Looking forward to attending my first database conference, SIGMOD 2025 (‪@sigmod2025.bsky.social‬), in Berlin starting this weekend. We will present four works, all of which tackle the challenge of making data-centric systems reliable, and together have found more than 100 bugs in important systems!

.‪@abhikrc.bsky.social is kicking off the Fuzzing and Software Security Summer School 2025! Looking forward to a week full of exciting talks and tutorials as well as interactions.

🚀 I'll be launching the Formal Methods Engineering Lab (manchester-fme.github.io) – and I am hiring! If you’re interested, feel free to reach out.

Our USING KEY variant of recursive CTEs has landed in DuckDB 1.3 Formerly an off-the-beaten-path researchy idea, now available in a real off-the-shelf DBMS. Hooray! 🎉 duckdb.org/2025/05/23/u...

This is something we've been working on for a while, and now are thrilled to share. Veil: the first foundational framework that combines SMT-based and interactive proofs about distributed protocols, seamlessly, in Lean! Tool: github.com/verse-lab/veil Paper: verse-lab.github.io/papers/veil-...

Followed the call of an Oriental Pied Hornbill that lead me to a pair of Buffy Fish Owls. Only my second time to see wild owls in Singapore!

An exciting talk by Armando Solar-Lezama on applying PL ideas for ML, with applications in robotics and computational biology. You can’t do cooler than that. Also, a second SIGPLAN Milner Award recipient giving a talk at NUS in the last two weeks.

One week today is the deadline for expressing your interest to attend Programming Language Implementation Summer School (PLISS) -- we have a great program, if I do say so myself! pliss.org/2025/

Just got back from NUS Research Week. I had a wonderful time. Thanks to @ilyasergey.bsky.social for being an amazing host. Everyone should get working on ICFP/SPLASH submissions... it's going to be a great conference!

The deadline to submit a workshop proposal for ICFP/SPLASH 2025 is **Thursday, January 16** less than a week away! conf.researchr.org/track/icfp-s...

It was a a delight to hang out with these fine friends during the Computer Science Research Week at NUS. My first trip to Singapore - what a city! I'm delighted that #OOPSLA / #SPLASH and #ICFP will take place there in October.

Completed my second voyage with NUS CS students! While we visited many natural gems, pollution as well as exploitation of natural resources are always shocking. I'm often thinking how our research could help address some of these sustainability challenges.

Hello everyone - this is first post in Bluesky - it seems lot of friends are moving to Bluesky - so I am also creating a home here. I am a Professor of Computer Science at National University of Singapore working on Software Engineering and Security. Find me in the web abhikrc.com
