    🎉 Excited to share our new work MuRGAt! We show that high multimodal reasoning accuracy does not guarantee faithful grounding — MLLMs often answer correctly while hallucinating where their facts come from. Multimodal fact-level attribution remains a big open challenge! More

    Huge congratulations to my PhD advisor @mohitban47 on being named an ACL Fellow! 🎉 I’m deeply grateful for your mentorship and guidance. Also congrats to Yue, the very first professor who introduced and guided me into the world of NLP research. Both honors are truly well
