Tiange Xiang 向天戈

I am a CS Ph.D. student in Stanford Vision and Learning Lab (SVL).
I'm advised by Sequoia Capital Prof. Fei-Fei Li (computer science) and
co-advised by James H. Clark Prof. Scott Delp (biomechanics).

I received my Bachelor's degree from The University of Sydney, where I was fortunate to work with Prof. Weidong Cai. I was awarded Honors Class I and The University Medal.

I do research on AI & Computer Vision.
