Undergraduate Research Assistant | Advisor: Prof. Mi-Hwa Song | Dec. 2025 - Present
Details
- Present and discuss recent RAG and multi-agent systems literature in weekly lab meetings, and contribute to an industry-academia collaboration project applying RAG and MAS to domain problems.
- Led a first-author research project on automated corporate knowledge-graph construction and GraphRAG-based multi-hop risk reasoning, published and presented as a poster at KCC 2026.
- Built an ontology-constrained extraction pipeline and a dynamic graph-traversal module for the system, and proposed Cross-Hop Reachability, a novel metric capturing multi-hop retrieval integrity that standard RAG metrics overlook.

Details
- Designed an ontology-driven pipeline that automatically constructs a corporate relationship knowledge graph from SEC 10-K filings.
- Performed multi-hop risk reasoning by tracing only explicitly connected graph paths, refusing to answer when no valid path exists to control hallucination.
- Proposed Cross-Hop Reachability, a novel metric quantifying multi-hop retrieval integrity that standard RAG metrics fail to capture.

Role: Leader / Data & AI Engineer | Mar. 2026 - Present
๐ GitHub Organization
Details
- Design and lead the end-to-end architecture of a GraphRAG workspace analyzing corporate relationships and multi-hop financial risk from unstructured data.
- Architect a LangGraph multi-agent system over a hybrid store (Neo4j, ChromaDB, MySQL), routing queries by the structure each sub-question requires.
- Engineer an ontology-driven pipeline extracting knowledge triples from DART filings and news, with a layered ontology balancing schema stability against graph sparsity.
- Enable multi-hop risk reasoning that traces explicit graph paths and refuses to answer when no valid path exists, grounding every insight in verifiable evidence.

๐ GitHub Organization
Details
- Built a conversational dining agent on LangGraph with an orchestrator routing intents to a ReAct-based Discovery subgraph and a transactional Action subgraph.
- Implemented a 'collect-confirm-execute' Human-in-the-Loop flow persisting state across turns, guaranteeing confirmation before any irreversible action.
- Developed an MCP server exposing external tools through a standard interface, decoupling agent logic from backend systems.

Role: AI Perception & Agent Engineer | Jun. 2026 - Jul. 2026
๐ฅ 1st Place Award, Singapore AIยทSW Industry-Academia Project
Details
- Developed an embodied agent sorting cubes in Menlo Research's Asimov warehouse simulation without pre-mapped coordinates, pairing LLM decision-making with deterministic execution code.
- Engineered the perception pipeline estimating sign coordinates from robot pose, VLM-observed direction, and blob-size distance โ replacing the forbidden ground-truth scene state.
- Cut search latency via asynchronous VLM requests during continuous 360ยฐ scans, and diagnosed the fixed-distance assumption as the pipeline's key limitation.

Details
- Integrated a hybrid retrieval mechanism (SQL + ChromaDB) with BGE Cross-Encoder reranking to deliver high-precision panel extractions from 630,000+ survey records provided by PMI.
- Engineered a FastAPI backend with SQLite-based state synchronized to LangGraph's checkpointer, enabling persistent multi-turn drill-down sessions.
