Research

His research interests are broadly in artificial intelligence, with emphasis on computer vision and machine learning. Much of his research is about 2D image generation, completion and translation, 3D scene reconstruction, generation and completion with the goal of building intelligent machines, capable of rebuilding a photorealistic virtual world via generative AI.
