Hello! I’m Yunkang Cao (曹云康), a Ph.D. candidate at Huazhong University of Science and Technology (HUST), where I am honored to be working under the guidance of Prof. Weiming Shen. I am also grateful for the opportunity to visit Politecnico di Milano (Polimi) for one year, working under the supervision of Prof. Giacomo Boracchi.

My academic research primarily focuses on Deep Learning and Computer Vision, with a particular emphasis on Multi-modal Anomaly Detection. Recently, my work has concentrated on leveraging foundational models such as vision-language models for anomaly detection tasks, as well as exploring Zero/Few-shot Anomaly Detection. Beyond visual anomaly detection, my long-term goal is to enhance intelligent visual systems with reasoning and planning capabilities to address and recover from open-world anomalies. This approach is designed to improve the robustness and safety of applications in fields like intelligent manufacturing and autonomous driving. If you find my research interesting, I would love to connect! Feel free to reach out if you have any questions or would like to discuss my work. 😊

Additionally, I am currently exploring postdoctoral opportunities. If you know of any openings or are interested in potential collaborations, please don’t hesitate to email me!
