About Me

I am a Senior Research Scientist at Picsart AI Research. My current research interests lie in Generative AI and efficient model.

I received my Ph.D degree from Electrical and Computer Engineering Department, Northeastern University, advised by Prof. Yun Fu. During my Ph.D. career, I focus on studying Computer Vision and Deep Learning, especially learning with efficient model, Face and Pose Estimation, Multi-modality, super-resolution, agriculture vision, etc. Please find the webpage of our lab here SmileLab. I have also spent time as a founding member in AI-startups (Giaran acquired by Shiseido, Ainnovationlabs). Besides, I spent three months as a computer vision engineer in Zebra. In 2023, I got a great starting stage in Topazlabs as a deep learning researcher, working on generative ai and its optimization on local devices.
