Chuhan Wang Hi there! 😄 I'm Chuhan (you can also call me Holly), a Ph.D. student at the University of Notre Dame, fortunate to be advised by Prof. Meng Jiang and affiliated with the DM2 Lab. My research focuses on improving the faithfulness and trustworthiness of multimodal large language models, aiming to make their reasoning more reliable and better grounded in what they actually perceive. Feel free to reach out for any form of communication or collaboration! Email / CV / Google Scholar / Github / LinkedIn |
