Responsibilities include:

• Led the design and optimization of the rendering system for the new version of the high-fidelity simulation platform SAPIEN, supporting both rasterization and ray tracing pipelines, with batching rendering optimization implemented in Vulkan.
• Designed and implemented a physically based material system, featuring diffuse/specular IBL, GGX BRDF/BTDF with material layering, and multi-scattering energy compensation for physical correctness.
• Designed and implemented a Blender-compatible node-based shading system, enabling flexible material authoring and seamless reuse of Blender workflows.
• Implemented rasterization shaders for Gaussian Splatting, integrating point-based neural scene representations into the real-time rendering pipeline.

Responsibilities include:

• Maintained a simulation pipeline for active stereo depth sensors, supporting realistic depth and infrared signal generation.
• Improved the performance of Vulkan-based rasterization pipelines, focusing on GPU efficiency and real-time rendering throughput.
• Implemented rendering system features including multiview rendering, geometry instancing, shadow catchers, reflection probes, and tone mapping.
