Dr. Chen XU is dedicated to applying mathematical statistics, signal processing (including Fourier transform, and wavelet analysis), machine learning, as well as their applications in other fields. His past research topics include stochastic discount factor models, time series analysis, fund research, etc. Now he mainly works on supervised learning algorithms in applied mathematics and analyzing the convergence of reinforcement learning algorithms using probability theory, time series, and topology. He has published several papers as the first or corresponding author in top-tier journals and international conferences.

徐晨博士致力于應用數理統計、信號處理（傅里葉變換、小波分析）、機器學習等方法以及它們在其他領域中的應用。以往研究課題包括隨機貼現因子模型、時間序列分析、基金研究等。當前工作主要包括使用概率論、時間序列、拓撲等工具對強化學習算法收斂性進行分析，以及監督學習算法在應用數學等領域的應用研究。他以第一或通訊作者在中國數學會推薦的T1類期刊或中國計算機學會推薦的A類會議(CVPR)上發表論文。
