My name is Lihu Chen (陈立虎), and I am currently a Research Associate at Imperial College London.
Before that, I did a one-year postdoc at Inria Saclay. I obtained my PhD at DIG team of Télécom Paris, which is a member of Institut Polytechnique de Paris. I was co-supervised by Fabian Suchanek and Gaël Varoquaux.
My research primarily focuses on natural language processing (NLP) and large language models (LLMs). I am dedicated to developing efficient, reliable, and open-source models and tools, with a particular emphasis on information extraction and biomedical applications. Specifically, my research topics include:
- Large vs Small: Collaborative AI Modeling Approaches (Frugal AI). In our survey, we systematically examine the collaborations between LLMs and SMs. My research will primarily build upon this foundational concept, focusing on leveraging the complementary strengths of both LLMs and SMs.
- Trustworthy AI Systems. I am interested in LLM security, disinformation detection, uncertainty estimation, and knowledge mechanism of LLMs.
- Efficient Knowledge-Augmented LLMs. LLMs may struggle with tasks that require domain-specific expertise or up-to-date information. I aim to explore cost-effective methods for enhancing reasoning capabilities, e.g. logical reasoning and medical applications.
- Long-term Research Question: Can AI Think Like Humans (or Beyond): New Architectures? Multimodality? New Learning Objectives? Neuro-symbolic Integration? We’ll see!
