Cambridge, Massachusetts, United States
Summary
🤩
Rockstar🎓
Top SchoolSai Bangaru is a Senior Research Scientist at NVIDIA with eight years of experience bridging cutting-edge research and production systems in differentiable rendering, real-time path tracing, and neural rendering. He completed a PhD at MIT CSAIL under Fredo Durand and builds compiler-level support for differentiable programming—most notably adding forward-mode automatic differentiation and a differential type system to the shader compiler Slang. Sai’s work spans practical real-time graphics, physically based modeling, and perception applications, and he has a track record of shipping research prototypes into NVIDIA’s rendering stack following internships and research roles across industry and academia. Based in Cambridge, MA, he combines deep theoretical training with hands-on systems engineering, often tackling problems that require changes to compilers and IRs rather than only top-level models.

Making it easier to work with shaders
Role in this project:
Back-end Developer
Back-end DeveloperContributions:164 reviews, 22 commits, 276 PRs in 7 months
Contributions summary:Sai implemented core functionality related to forward-mode automatic differentiation within the shader compilation framework. Their work included adding syntax for marking functions for differentiation, developing a new type system, and adding support for various operations like vector arithmetic, control flow, and function calls. The contributions involved modifying the compiler's intermediate representation (IR) and introducing a differential type system to support the generation of derivative functions. The user significantly expanded the compiler's capabilities for auto-differentiation, enabling the handling of more complex shader code.
