Application Security Researcher

Focused on SAST, IAST, and practical open-source security tooling.

I work on program analysis for security: building static and interactive analysis tooling that scales to real codebases, and doing vulnerability research on the JVM.

• CAST Attack: Ghost Bits in Java — Black Hat Asia 2026 Briefings, Singapore (Review Board top must-see selection)

• Cross-language code property graphs — merging per-language CPGs into a single graph with cross-language edges, so taint flows survive a language boundary
• Interprocedural taint analysis — cross-file and cross-module propagation, FQN-exact call resolution, sink-rooted result aggregation
• LLM-assisted auditing with deterministic verdicts — models for naming and labelling, exploitability decided by an engine, not by a prompt
• Build-from-source verification — reconstructing a runnable target from its repository, then confirming findings with IAST, OAST, and sanitizer signals
• JVM vulnerability research — bytecode and runtime semantics, gadget chains, instrumentation

• Role: Security researcher and tool builder
• Primary Domains: SAST, IAST, program analysis, JVM security
• Preferred Stacks: Java, Kotlin, Scala, Python, Go, Rust, TypeScript
• Environment: Linux, Docker, HPC batch clusters (PBS)
