👋 About Me

Hello! This is Enneng Yang. I’m currently a Postdoctoral Fellow at Shenzhen Campus of Sun Yat-sen University, China, advised by Assoc. Prof. Li Shen. Before that, I received the PhD degree (June 2025) from Northeastern University, China, advised by Prof. Guibing Guo. From March 2024 to March 2025, I am a visiting Ph.D. student in Prof. Jie Zhang’s group at Nanyang Technological University, Singapore.

My research interests lie in large language models, machine learning, and recommender systems. More specifically, I focus on:

• Large Language Model: continual pretraining/finetuning, knowledge editing
• Machine Learning: model merging, multi-task learning, continual/incremental learning, data-free learning, dataset/knowledge distillation
• Recommendation System: multi-task/multi-scenario recommendation, sequential recommendation, OOD recommendation

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