Hello! This is Yizhou Dang (党翌洲 in Chinese). I am currently a third-year Ph.D. student at Software College of Northeastern University, Shenyang, China. I am fortunate to be advised by Prof. Guibing Guo. Before that, I earned my B.E. degree in 2023 at the same institute. I am honored to work closely with Enneng Yang, Yuting Liu, and Yong Liu.

My research interests focus on AI for science (enzyme design) and recommender systems (sequential recommendation and LLM-based recommendation). I am particularly interested in data-centric methods, such as data augmentation and data synthesis.

Please feel free to contact me by email if you have any questions or are seeking collaborations.

🔥 Our team is seeking self-motivated students (including remote internships, undergraduates, graduate students, and other candidates) to join research on recommender systems, LLMs, and AI for science, with the goal of publishing high-quality academic papers. If interested, please email me your resume.
