Welcome!
Hi, nice to meet you! Iβm Xu Jundong, an incoming PhD Student at the National University of Singapore (NUS) CTIC lab, working under the supervision of Prof. Mong-Li Lee and Prof. Wynne Hsu. I am also mentored by Dr. Hao Fei. Previously, I earned a Master of Computing from NUS and a BSc from University College London (UCL).
My work focuses on enhancing the symbolic reasoning capabilities of AI systems. I aim to develop methods that enable AI to perform systematic, reliable, and deterministic inference, bridging the gap between data-driven learning and structured logical reasoning.
I actively seek interdisciplinary collaborations and welcome discussions with researchers who share an interest in AI, logic, and cognitive systems. Feel free to reach out via email to exchange ideas!
