I’m a Postdoctoral Research Fellow at the Lassonde School of Engineering, York University, in Toronto. My research is on agentic software engineering: how humans interact with agents, and how different agents and tools collaborate to carry out complex software engineering tasks.
Research focus
- Agentic SE. Human–agent interaction, and multi-agent / multi-tool collaboration on end-to-end engineering tasks.
- Trustworthy LLMs for code. Reliability of foundation models for text-to-code, unit test and test-oracle (assertion) generation, program repair, code summarization, and code translation.
- SE for AI. Vulnerabilities and checker bugs in ML/DL libraries, benchmarks for vulnerability detection, and testing static analyzers and vision-language models.
- Explainable defect prediction. Actionable and stable defect predictors that tell developers what to change, not just where.
Experience highlights
- York University — Postdoctoral Research Fellow, Lassonde School of Engineering (May 2026–present).
