Ahmed Abdelreheem

I am a CS Ph.D. candidate at King Abdullah University of Science and Technology, working under the supervision of Prof. Peter Wonka. My research focuses on the intersection of 3D vision, natural language, and computer graphics, with an emphasis on building models that reason about 3D scenes and objects through language. I am particularly interested in spatial reasoning, object-centric representations, and the use of LLMs and 3D LLMs for 3D understanding and editing.
