My research focuses on interactive tools and representations for visual creation, editing and exploration. I work with artistic graphical representations (such as sketches, 3D models, images and videos), and enjoy designing interactive graphics workflows for creative tasks that are convenient, intuitive and fun.
Current Interests: creative interfaces, generative AI, 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 realistic capture representations under the awesome guidance of Masha Shugrina.
