Photoshop
Rotate Object
Rotate an object in a photograph to change its angle and perspective. My work on the feature included the custom Gaussian splatting renderer powering its interactive 3D preview.

About
Before Canva, I spent seven years at Adobe Research, working on neural rendering methods and production rendering systems. Earlier, I worked on shading systems for MoonRay at DreamWorks, with film credits on Trolls, The Boss Baby, and Trolls Holiday.
I earned an M.S. in Computer Science from UC San Diego (2015), focused on computer graphics and advised by Ravi Ramamoorthi.
Selected work
Rendering systems shipped in Adobe’s creative tools.
Illustrator
3D & Materials
Ray-traced lighting and materials for vector artwork. I contributed to the renderer and co-developed the neural denoiser introduced with Illustrator’s redesigned 3D tools.
Dimension
GPU ray tracing
GPU ray tracing for Dimension, built on OptiX and RTX. I led the four-person team that took the renderer from a research prototype into production.
Substance 3D
Vulkan ray tracing & denoising
I helped bring Vulkan ray tracing and neural denoisers I co-developed to Substance 3D Stager and the then-beta Substance 3D Viewer, supporting interactive previews and faster final renders.
Selected research
Generative Neural Materials
A diffusion model that generates renderable neural materials from images. I co-developed the method, built the synthetic-data pipeline, and trained the decoder and diffusion model.
RNA: Relightable Neural Assets
Compact neural assets that preserve complex appearance as viewpoint and lighting change. I developed the representation and integrated it into a production path tracer.
