Rajath Kumar is a founding research scientist based in New York with 11 years of experience building multimodal foundational models and leading applied research teams. Previously a Senior Applied Scientist and Tech Lead at Amazon working on AGI initiatives, he combines deep academic training from Columbia (EE) with hands-on production ML experience across speech, vision, and multimodal systems. His early research spanned neural acoustic processing, music source separation, and ECoG-based ASR, and he has taught and developed numerical methods and Python course materials used in Columbia classes. An active practitioner of reproducible notebooks, his GitHub contributions include educational Jupyter/IPython materials for numerical methods and Python that reflect a strong commitment to clear technical teaching alongside research. Colleagues describe him as a pragmatic scientist who moves state-of-the-art models toward real-world products while keeping an educator’s attention to explainability and implementation detail.
