Xiaowen Ma

I receive the B.S. and master degrees in remote sensing image processing and machine learning from Zhejiang University, Hangzhou, China, in 2021 and 2024, respectively. I am now an AI Researcher with Huawei’s Noah’s Ark Lab, Shanghai, China.

I have published serveral research papers and serve as a reviewer including NeurIPS, ICML, ICLR, ICCV, ECCV, CVPR, TGRS, ISPRS, PR, KBS, etc. My research interests include remote sensing, time series analysis, computer vision, and multimodality.

Recently, I am recruiting research interns in Huawei Noah’s Ark Lab to explore AI technology including VLM, Large Model Reasoning Acceleration, etc. Feel free to contact me if you are interested!
