Tianchang Shen

I am a 3rd year Ph.D. student at University of Toronto advised by Prof. Sanja Fider. I'm also a research scientist at Nvidia. My current research interest is in AI-assisted 3D content creation.

I graduated from University of Toronto in 2019, where I did my B.S. thesis advised by Prof. Tim Barfoot and Prof. Angela Schoellig. Prior to that, I also interned in Qualcomm.
