Personal Statement

I hold a Ph.D. in Computer Science, having earned my master's and doctoral degrees from Dalian University of Technology in 2018 and 2023, respectively. My doctoral research was conducted in the DUTIR lab under the supervision of Prof. Yuanyuan Sun and Prof. Hongfei Lin.
Currently, I am a visiting fellow (postdoctoral researcher) at the National Institutes of Health (NIH), working with Dr. Zhiyong Lu.
My research interests center around Large Language Models (LLMs), Knowledge Representation and Reasoning (KRR), and Data Mining (e.g., Network Embedding). My long-term goal is to develop AI-driven computational methods that integrate structural knowledge from diverse resources to advance biomedical knowledge discovery and improve healthcare outcomes.

At present, my research topics include

Application of LLMs in Biomedicine (LLM Application)
Reinforcement Learning in LLMs (LLM Finetune)
Multi-modal Biomedical Knowledge Graph (Biomedical KG)
Continual & Incremental Representation Learning (Continual KR)
