Experience

Summer Research Intern

CCNCS, PES University

June 2025 - July 2025
  • Designed XJailGuard, a modular LLM security framework to detect multi-turn and cross-lingual prompt injection attacks in transformer-based models.
  • Built multilingual classification pipelines using PyTorch and Hugging Face, incorporating sliding-window contextual memory for adversarial intent detection.
  • Improved jailbreak detection accuracy from 8-12% baseline to 91-93% through layered input/output filtering and zero-trust validation.
  • Integrated SHAP-based Explainable AI and evaluated performance using false positive/negative rates and latency benchmarks; authored for ICICC 2025 publication.
