LLM AGENTS · SECURITY

Agentic Coding Reliability · NSF Cybersecurity-Funded

An NSF-funded study of whether software written by LLM coding agents is actually safe to ship. I rebuilt a classic UNIX reliability fuzzer into faster research tooling, tested a 12-program corpus of utilities including grep, make, and ptx, and root-caused real memory-safety and denial-of-service bugs.

  • 12 programs · grep, make, ptx + more
  • 4× faster evaluation tooling
  • 10+ source defects investigated
  • uutils ptx · 29× faster · 19% less peak memory

REACT NATIVE MOBILE · HEALTH AI

Awaaz-e-Sehat

A React Native mobile app deployed in hospitals for seven months, using Whisper fine-tuned with LoRA on local Urdu speech to create structured records and surface dangerous maternal-health conditions.

  • React Native · 500+ records
  • 96% accuracy
  • 60% less documentation time
  • 7%→40% detection · 300+ alerts

OPERATING SYSTEMS

Evaluating Linux Schedulers

An empirical comparison of Linux EEVDF and CFS across latency-sensitive and CPU-bound workloads, combining application-level measurements with eBPF traces under controlled contention.

  • EEVDF · 4–6× lower p99.9 wakeup latency
  • EEVDF · up to 65% higher Redis GET throughput
  • CFS · 13–59% lower HTTP latency
  • CFS · 10–15% higher 7-Zip throughput

VIDEO SYSTEMS · GENERATIVE AI

VIDER Video Reconstruction

A model-agnostic streaming framework that sends sparse keyframes over long-haul links and reconstructs intermediate video frames near the viewer.

  • 97.69% avg. bandwidth savings
  • 0.83 avg. ViSiL similarity
  • 28-video evaluation
  • Beat H.264 CRF 50 on savings + similarity
