Muhammad Usama Saleem

I'm an Applied Scientist II at Amazon, where I develop large-scale multimodal AI systems for real-world operational and customer experiences. I received my Ph.D. in Computer Science from the University of North Carolina at Charlotte in 2026, advised by Prof. Pu Wang in the GENIUS Lab. I was previously a Research Scientist Intern at Google's Extended Reality (AR/VR) team. My work includes a U.S. Patent on 3D human pose and movement estimation from monocular images.

My research focuses on building multimodal foundation models that unify real-time perception with high-fidelity synthesis. I aim to develop context-aware AI systems capable of perceiving, reconstructing, and interacting with complex human behavior across both physical and virtual environments. My work centers on multimodal motion synthesis frameworks that enable controllable, high-quality 3D human animation for real-time applications, as well as 3D human pose estimation and mesh reconstruction using generative masked modeling. Ultimately, I seek to leverage these generative foundations to create AI systems that can both understand human behavior in the physical world and synthesize interactive digital counterparts within immersive XR environments.
