I am Sihan Ma, a Ph.D student at The University of Sydney (USYD), supervised by Prof. Dacheng Tao and Dr. Jing Zhang. Formerly, I was a research intern in JD Explore Academy, where I worked closely with Dr. Qiong Cao. Before that, I obtained my MPhil degree at USYD, and bachelor’s degree at Wuhan University (WHU). I worked closely with Prof. Lefei Zhang at WHU.

My research interests include 3D human-centric visual perception and generation, human-object interaction, portrait image matting.
