Research Highlights
1. Simon's Congruence Pattern Matching & Mining: We design efficient algorithms for pattern matching and mining under Simon's congruence and improve subsequence-based pattern discovery.
  • Pattern Mining under Simon's Congruence [DLT'25]
  • Simon's Congruence Pattern Matching [TCS'24]
  • On Simon's Congruence Closure of a String [TCS'23]

  • 2. LLM Watermarking: We develop robust watermarking techniques for LLMs and AI-generated codes focusing on provenance, quality preservation, linguistic awareness and resistance to attacks.
  • Sequential Behavioral Watermarking for LLM Agents [NeurIPS'26] 요약
