Karran Pandey

I'm a third year CS Ph.D. student at the University of Toronto advised by Karan Singh. My research focuses on building novel creative tools to model, edit and understand artistic graphical representations (such as sketches, 3D models and images). I enjoy using machine learning and geometry processing algorithms to design creative computer graphics workflows that are convenient, intuitive and fun.

Current Interests: geometric modeling, creative interfaces, non-photorealistic rendering

Prior to beginning my Ph.D, I did my masters thesis and worked as a Research Assistant at the Indian Institute of Science, with Vijay Natarajan. I graduated with an M.Sc. in Mathematics and a B.E. in Computer Science from BITS Pilani, Hyderabad, India in 2019.

In the past, I have interned at Adobe Research, working on designing intuitive edit handles for text-to-image diffusion models with an amazing team of collaborators in Paul Guerrero, Niloy Mitra, Matheus Gadelha and Yannick Hold-Geoffroy.
