I am currently at the Artificial Intelligence Research Institute of Soochow University, advised by Assoc. Prof. Juntao Li(李俊涛) and Prof. Min Zhang(张民).

Before this, I received my Bachelor’s degree (2018-2022, computer science) from Soochow University.

I am currently working as a research intern at Shanghai AI Laboratory General Technology Research under the mentorship of Xiaoye Qu(瞿晓晔) and Yu Cheng(成宇).

🤔 My research interests are primarily focused on exploring various challenges related to the dynamic of “time” in machine learning. Currently, my main focus is on Large Language Models (LLMs), covering the following topics:

• Adaptation and Generalization: Focusing on the reasons behind model degradation in time and exploring the strategies to improve temporal generalization and update the knowledge without catastrophic forgetting of old knowledge.
• Trustworthiness and Reliability: Investigation into the behavior of LLMs when encountering knowledge conflicts and exploring methods to mitigate knowledge conflicts of old knowledge as we update LLMs with new knowledge.
• Complex reasoning: Research on equipping LLMs with human-level temporal reasoning and commonsense. This involves basic temporal concepts understanding and intricate temporal interpretations and computations.

📖 Can the progress of civilization, and the advancement of technology truly transcend time? Or are we just endlessly pursuing the elusive dust in the hourglass?

🤝 I’m looking for a PhD position in 2025 Fall. Don’t hesitate to email me if there is a potential opportunity!
