Search agents · 2026

Sieve: Search, Inspect, Fetch

Boolean search narrows the candidates, inspection exposes document structure, and fetch reads only the selected sections.

Teaching & mentoring

INFS7410 · Information Retrieval and Web Search

I coordinated and lectured INFS7410 at UQ, teaching 120+ Master's students across classical IR, dense retrieval, LLMs for search, RAG and evaluation. I mentored students on retrieval, RAG and biomedical NLP projects; several have progressed to PhD scholarships and SIGIR/ECIR papers.

Opportunities

Let's work together.

I welcome research collaborations and conversations about web search for AI agents, search agents, retrieval systems, efficient RAG, trustworthy evaluation and biomedical evidence technologies.
