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.
