Seeking a PhD position starting in Fall 2025.
Please feel free to contact me via email for any discussion!

I am a senior undergraduate student at National Taiwan University (NTU) in the Department of Electrical Engineering, and a research assistant in the NTU Robot Learning Lab, working with Professor Shao-Hua Sun and co-advised by Professor Hung-yi Lee. My research interests focus on Large Language Models’ Creativity and Collaboration between Humans and AIs. Our projects also include multi-agent systems, in-context learning, and reinforcement learning from human feedback (RLHF).

I am currently a visiting student researcher at the University of California, Los Angeles (UCLA), in Professor Nanyun Peng’s PLUS Lab, where I am further exploring the creativity and evaluation of LLMs.

Large language models (LLMs) have shown exceptional proficiency in natural language processing but often fall short of generating creative and original responses to open-ended questions. To enhance LLM creativity, our key insight is to emulate the human process of inducing collective creativity through engaging discussions with participants from diverse backgrounds and perspectives. To this end, we propose LLM Discussion, a three-phase discussion framework that facilitates vigorous and diverging idea exchanges and ensures convergence to creative answers. Moreover, we adopt a role-playing technique by assigning distinct roles to LLMs to combat the homogeneity of LLMs. We evaluate the efficacy of the proposed framework with the Alternative Uses Test, Similarities Test, Instances Test, and Scientific Creativity Test through both LLM evaluation and human study. The results show that our proposed framework outperforms single-LLM approaches and existing multi-LLM frameworks across various creativity metrics.
