lessModern hardware is parallel and is increasingly relying on parallel programming to achieve
both performance and energy efficiency. However, today’s parallel programming places a disproportionate burden on developers, requiring them to design and fine-tune parallel execution strategies across diverse hardware platforms and varying program inputs. I postulate that optimizing compilers can relieve developers from this burden by automatically reasoning about parallel execution strategies while also enforcing correctness properties. Achieving high parallel performance across modern hardware requires selecting an effective parallel execution plan, including how and where parallelism should be expressed and implemented. To automate this selection process, I introduce the Parallel-Semantics Program Dependence Graph (PS-PDG), a compiler abstraction
that captures developer-encoded parallel semantics alongside compiler-derived analysis. PS-PDG
enables compilers to override suboptimal execution plans with superior alternatives. While static
execution-plan selection is effective for regular workloads, irregular and input-sensitive applica
tions require runtime adaptation of parallel granularity. To address this challenge, I introduce the
Heartbeat Compiler (HBC), a compilation system that automatically translates high-level fork
join parallelism into binaries capable of dynamically controlling task granularity through heartbeat
scheduling to eliminate the need for manual task-size tuning. Beyond performance, parallel C++
applications also face severe memory-safety risks arising from operations on data collections, in
cluding iterator invalidation. These bugs are difficult for existing tools to detect precisely and
become even harder to diagnose under nondeterministic thread interleavings. To address this chal
lenge, I introduce Ledger, a data collection-oriented static analyzer that provides high-precision
detection of invalidation vulnerabilities in programs that operate on complex data collections.TIME Wednesday, June 3, 2026 at 2:00 PM - 4:00 PM

lessThere is growing momentum—from industry, government, and academia—to use AI for automating cybersecurity tasks. Yet practitioners remain skeptical: while 87% of security leaders expect AI to enhance their roles, only 9% believe it will replace significant parts of them. This gap stems from two fundamental barriers: limited capability and lack of trust. In this talk, I present my research on addressing these barriers through explainable AI. I first introduce StateMask, a method that automatically identifies critical decision steps in AI agent trajectories, enabling security professionals to understand why an AI-generated patch succeeded or failed. A user study with 41 experienced developers shows that 89% find our explanations aligned with their reasoning. I then present GPO, which leverages these explanations to synthesize high-quality training data without expensive expert annotation, thereby improving model capability. GPO-trained open-source models achieve performance competitive with leading commercial models on vulnerability patching, and its extension, EntroPO, ranks 1st on SWE-Bench Lite among all open-weight models. I conclude by discussing future directions toward building AI systems that are robust to imperfect data, trusted by security professionals, and capable of tackling real-world cybersecurity challenges.

lessHi CS++ PhD students, faculty, staff, post-docs,
We will be hosting a BBQ to celebrate the end of this academic year!
When? Friday, June 12, 5-7 pm
Where? North side of Evanston Centennial parkWe will be cooking up American BBQ classics with plenty of snacks and cold drinks to go around (vegetarian and vegan food included).
Please RSVP by 5 pm on Thursday, June 11, so we can prepare enough food for everyone.
We have an RSVP list so that folks (signed in) can see who else is going. If you don’t see a friend or labmate signed up, make sure to reach out and invite them!
Looking forward to seeing y’all there!
