Kai Zhao, Ph.D.


University of California, Los Angeles

Kai Zhao is currently a postdoctoral researcher at UCLA working with professor Kyung Hyun Sung on medical image analysis. Before joining UCLA, he was a senior research scientist in Tencent Youtu lab. He received his Ph.D from Nankai University in 2020, under the supervision of professor Ming-ming Cheng. Before that, he spent 7 wonderful years in Shanghai University where he got his BS and MS in 2014 and 2017, respectively, under the supervision of Wei Shen (now professor at Shanghai Jiaotong University).

His research interests broadly lie at the intersection of Computer Vision ,Geometry , and Machine Learning . He co-authored over 20 research papers on top-tier venues in the field of AI and computer vision, with over 4,000 citations on Google Scholar. His research on palmprint recognition was highlighted by MIT technology review, and applied to WeChat palm payment. He is an active contributor to open-source projects such as PyTorch and mmdetection.
