Di Lu is a Graphics Profiling Tools Engineer at NVIDIA, where she works on the Nsight Graphics team developing GPU Trace. She focuses on how GPU hardware executes Vulkan/DX12 workloads, building tools that reveal performance behavior at the instruction and shader level. Her interests center on hardware–software interactions for real time ray tracing and neural shading technologies. Di recently led a GPU Trace lab session at SIGGRAPH 2025, sharing techniques for diagnosing shader performance bottlenecks with game developers.

Martin heads up Raytracing at NVIDIA as a Senior Director of Engineering. As one of the original authors of OptiX in 2008, and after a brief stint in hardware architecture working on the Maxwell SM, Martin went on to lead design and development of the software stack that powered the launch of RTX hardware raytracing in 2018. His team's responsibilities today include the development of all of NVIDIA's raytracing APIs and platforms (DirectX, Vulkan, OptiX/CUDA, Switch 2), the continuous research of future raytracing capabilities in hardware and software, and direct work with partner ISVs in the gaming and professional applications space.
