Dr. Shuai Wang (Dylan Wang) is a Postdoctoral Research Fellow at the IELab, University of Queensland, Australia. His research lies in Information Retrieval (IR), Natural Language Processing (NLP), and Retrieval-Augmented Generation (RAG), with a focus on building efficient, reliable, and reproducible AI search systems. Dr. Wang has authored 20+ peer-reviewed papers in top-tier venues including SIGIR, WSDM, WWW, ECIR, EMNLP, and EACL, accumulating 1113+ citations with an h-index of 15. He completed his PhD at the University of Queensland in 2025 and currently serves as Course Coordinator and Lecturer for INFS7410 (Information Retrieval and Web Search) at UQ, and as the Communications Chair for SIGIR 2026. Representative work includes COCOM (a 5.69× RAG inference speedup), AutoBool (reinforcement-learned Boolean query generation for medical systematic reviews), and BERGEN/FeB4RAG (reproducible RAG evaluation tooling).

👋 Welcome!

I’m Shuai Wang (Dylan), a Postdoctoral Researcher at IeLab, UQ working on efficient LLM and retrieval systems. I build search and RAG methods that make AI systems faster, cheaper, and easier to evaluate, especially for evidence-based medicine and other high-stakes information work.

I completed my PhD under the guidance of Professor Guido Zuccon, Associate Professor Bevan Koopman, and Dr. Harrisen Scells.

🎓 Academic Background

  • Doctor of Philosophy - University of Queensland (2025) Read My Thesis
  • Master of Engineering Science - University of Queensland (2021)
  • Bachelor of Science - University of Western Australia (2019)

🔬 Research Focus

My work connects information retrieval, NLP, and AI systems:

  • Efficient RAG and LLM inference: context embeddings, KV-cache/memory optimisation, and unified retrieval-generation representations
  • Evidence-based medicine search: MeSH suggestion, screening prioritisation, seed-driven methods, Boolean query generation, and clinical question answering
  • Evaluation infrastructure: benchmarks and open-source tools for RAG and federated search, including BERGEN and FeB4RAG
  • Adaptive retrieval and ranking: 2D Matryoshka retrieval, prompt variation studies, and robust LLM-based rankers

👨‍🏫 Teaching & Mentoring

I serve as Course Coordinator and Lecturer for INFS7410 (Information Retrieval and Web Search) at UQ, teaching 120+ Master’s students across classical IR, dense retrieval, LLMs for search, RAG, and evaluation. Previously, I tutored INFS7410, INFS7205, and DATA7901/7902/7903.

I mentor students on retrieval, RAG, and biomedical NLP projects; several have progressed to PhD scholarships and SIGIR/ECIR papers. If you are interested in research collaboration, please reach out.

🌍 Industry Experience

Research Intern at Naver Labs Europe (Feb-July 2024). I co-led COCOM from method design and implementation to experiments and WSDM 2025 publication, reducing RAG inference cost by 5.69x at near-baseline answer quality.

💼 Job Opportunities

Since February 2025, I have been working as a Postdoctoral Researcher at UQ. I am open to academic and industry roles where efficient LLM systems, search/RAG, trustworthy evaluation, or biomedical evidence technologies are central. If this matches your team, please feel free to reach out.
