  1. Original code-generation prompt before BODE-GEN optimizationBODE-GEN optimized prompt with explicit examples and edge cases

    Tests Turn Prompting into Search

    Jul 2026, WritingWhat I learned building the evaluation pipeline behind BODE-GEN, where executable tests turn code prompting into an optimization problem.
  2. BODE-GEN correctness results compared with initial prompts, chain-of-thought, and OPRO

    BODE-GEN

    Dec 2025, ResearchBayesian prompt optimization for test-driven code generation, evaluated across HumanEval+ tasks and multiple code models.

  3. Knowledge Graph RAG Assistant

    May 2025, ProjectFor this team-built knowledge-graph RAG assistant, I generated and indexed 5GB+ of Wikipedia embeddings and refined FAISS retrieval toward a 10,000+ article knowledge base.
  4. Wedge and V-shape robot formations approaching participants during the Social Triangles study

    Social Triangles

    Oct 2023, ResearchAn IROS study of how multi-robot formation geometry shapes human navigation and approach behavior.
