Howdy! I’m Shuai Wang, a third-year PhD student who’s been swimming in the deep end of academia for what feels like forever. I’m under the eagle eyes of Professor. Guido Zuccon, A.Professor. Bevan Koopman, and Dr. Harrisen Scells.
I received my Bachelor of Science degree from the University of Western Australia in 2019, then obtained a Master of Engineering Science degree from the University of Queensland in 2021.
My research is strongly related to information retrieval and natural language processing (NLP). My PhD topic focuses on domain-specific applications (automation for medical systematic reviews), where I have been currently focused on the development of Automatic Mesh Term Suggestion, Screening Prioritisation, Seed-driven methods and Boolean query formulation. I also do some side projects on general IR and NLP tasks, such as Federated RAG, Fusion of Rankers etc.
I’m also a tutor at UQ, teaching courses like INFS7410 (information retrieval and web search). I’m not in it for the cash but for the chance to scout for other brainiacs to collaborate with. So, if you’re interested, let’s chat and see if we can cook up some research magic together!
I conducted my internship at Naver Lab Europe Feb-July 2024, with a research focus on Context Compression on Retrieval-augmented generation (RAG).
Job Opportunities
I’m expected to graduate at the end of 2024, and I’m currently looking for job opportunities in academia and industry. If you think I’m a good fit for your team, please feel free to contact me.
