From perception to understanding.
I’m Jeonghwan Kim, a Ph.D. candidate at UIUC’s BLENDER Lab, advised by Professor Heng Ji. I am a recipient of the Capital One Ph.D. Fellowship (2026–2027). My research is also supported by HERE Technologies. I worked with Shane Moon and Xin Luna Dong at Meta Reality Labs and Emre Eftelioglu at Amazon.
I study multimodal foundation models that perceive, ground, and reason about fine-grained spatial and temporal information. My work connects visual grounding, cross-modal alignment, and knowledge integration to make these systems more accurate and interpretable. Recently, I’ve been extending this work to visually grounded action policies for embodied AI and robotics.
I’m on the industry and academic job market for 2027. Get in touch if you would like to connect.
Research keywords: multimodal LLMs, multimodal post-training, visual tokenization & memory, vision-language-action.
