About Me

I am serving as a Research Engineer at OPPO US Research Center (InnoPeak Technology), Palo Alto, CA. My projects at OPPO range from learnable ISP (RAW-to-sRGB) and image/video super-resolution and enhancement for mobile devices, to 3D reconstruction for XR headsets. I also enjoy investigating network architectures and compression for on-device deployment. My work aims to advance the capabilities and applications of 2D/3D vision and machine perception technologies.

I earned my Ph.D. in Computer Science from Stevens Institute of Technology, with the guidance of my advisor, Professor Philippos Mordohai, in the field of computer vision, focusing on 3D reconstruction by binocular and multi-view stereo matching.

Prior to attending Stevens, I received my Bachelor’s Degree of Engineering from Northwestern Polytechnical University, and pursued Master’s Degree at Xi’an Jiaotong University, in China.
