My research builds novel creative controls for 3D-aware visual content creation, editing and exploration. Spanning diverse artistic mediums, my work ranges from accelerating traditional workflows in sketch-based design and 3D modeling to building new approaches for controllable photorealistic creation with 3D Gaussian splats and generative image / video models. My aim is to design interactive tools with new modes of creative control that make it convenient, intuitive and fun to manifest our visual imagination.
Current Interests: creative interfaces, generative image / video models, photorealistic content creation, geometric modeling, non-photorealistic rendering
In the past, I have interned twice at Adobe Research, working on creative controls for image and video generative models alongside an amazing team of collaborators in Paul Guerrero, Niloy Mitra, Matheus Gadelha and Yannick Hold-Geoffroy; and once at the NVIDIA Toronto AI lab, working on building creative tools for painting with 3D Gaussian splat brushes under the awesome guidance of Masha Shugrina.
