Tian Yu Liu

I am a PhD student at UCLA Vision Lab, advised by Prof. Stefano Soatto. My research interests lie in computer vision and machine learning. I also obtained my Bachelor of Science (Summa Cum Laude) from UCLA with a major in Computer Science and minor in Mathematics, where I worked with Prof. Baharan Mirzasoleiman and Prof. Alex Wong.
