Welcome! I'm Adheesh Juvekar

PhD Student at University of Illinois at Urbana-Champaign

I'm a Computer Science PhD student at PLAN Lab, UIUC, advised by Dr. Ismini Lourentzou. My research interests are in Multimodal Learning and Generative AI, with a focus on building models that can understand and create visual content in ways that are grounded, controllable, and interpretable.

I’m open to collaborations and always interested in discussing new research ideas, feel free to reach out via email. If you’re a self-motivated undergraduate (especially at UIUC) interested in working on Generative AI / multimodal projects feel free to reach out via email.

Research Areas

Multimodal Learning & Generative AI

I'm particularly interested in multimodal understanding, image/video generation. Currently, I am exploring hallucination mitigation in grounded vision-language models and controllable image/video generation with diffusion/flow-based models. I'm also interested in emerging direction at the intersection of generation and perception such as 3D-consistent generation, egocentric video understanding/editing as a step towards reliable and robust world models.
