Angel Xuan Chang


I am a postdoctoral researcher working with Tom Funkhouser at Princeton. Prior to this, I was a Ph.D. student in Computer Science at Stanford, in the Natural Language Processing Group. My advisor is Chris Manning. I'm working on text to 3D scene generation, and the ShapeNet project. In general, I am interested in the semantics of shapes and scenes, the representation and acquisition of common sense knowledge, and reasoning using probabilistic models. Some of my other interests include drawing and dance.
