Lucas Here! 👋
Hi, I’m Hung-Chun. I am a senior research assistant at Academia Sinica, Taiwan, working with Prof. Chuan-Ju Wang and Prof. Ming-Feng Tsai. My research interests lie in multimodal LLMs, information retrieval, conversational search, and graph neural networks. Currently, my research centers on developing multimodal LLMs to enable deeper human-AI interaction across diverse modalities and to generate personalized responses from multimodal feedback.
🎓 I received my M.S. in Data Science at National Taiwan University in 2023. During Master’s degree, I was fortunate to work with Prof. Chiu-Yu Wang at Academia Sinica and Prof. Che Lin at NTU.
🚀 I am actively seeking Ph.D. opportunities in the United States! my resume
